    Re: Frako caps in Grundig VS620 vcr

    New posts keep tracks of all posts since your last login: usually it's the last time you connected to badcaps, but after 30 min vBullettin relogins again and resets the post counter. I usually keep the front page, open all posts in other tabs and read them; if I can reply, I usually do. Sometimes replies take long time (I think a lot before writing, often I correct myself) so I read the number of posts present when I login for the first time, I reload the page and discover how many new posts there are.

    I love Bttf saga too , its time-space paradoxes and the critics Spielberg moves against society (time changes, technology too but mentality don't: people rode fast their horses in XIX century, drive fast their cars in XX and will drive fast their aeromobiles in XXI; there was, is and will be someone cheating the boss for money etc.).

    Colors: I think every era has its colors and they shouldn't change. Some old movies in DVD editions usually tend to boast too vivid colors and a perfect tonal balance: this ruins the original film and it's a shame to me, such as coloring b/w pictures like Turner did with Laurel & Hardy commedies.

    Film exposure: I don't know what kind of recovery is possible, perhaps with infrared or low light.

    VCR: my grandfather has a 2002 Sony 6 head VHS recorder, SLV-SE800 series, but he never uses it. I played with it a couple of times: slightly better picture than my Grundig (anyway you can't squeeze more than a simple VHS tape), stereo and low noise sound (big improvement over my Grundig's mono and noisy audio) but, accustomed to slow rewinding, I found the 60" rewind noisy and annoying (can't stop when I want).
    Keep looking for an used one, better an high end model.

    LVR: well, you wrote LVD ...
    Anyway I did know that Ampex pioneered linear video recording in early 50's, adapting the AEG Magnetophone audio recorder to video (in short: bigger and faster tape for higher bandwith). Despite simplicity, LVR didn't diffuse outside broadcast stations for a simple reason: it required a very long tape, longer than those used in elicoidal head systems such as Betamax and VHS; good tape costed a lot in early '70s and was a real challenge putting enough tape for a 2 hours recording into a cassette like the Compact Cassete Average Joe was accustomed. In fact, early system use reels, not cassettes.

      new posts usually works ok, but this time it didn't, as i never saw your reply listed.
      i go here and hit "new posts" and then see if there's anything i'm inerested in.
      such error has happened also on other forums as well, and equally very rare...

      vcr: you should ship your grandad's vcr to me..i promise i'll use it!..hehe...
      noisy...yeah...there really is a problem if somebody is sleeping in the room where you operate such vcrs...this new panasonic is like that...

      lvd and lvr...yeah...there was no longitudinal video disc, but all that disc discussion probably made me make a mistake.
      lvr by toshiba used 220 tracks of 17sec each.
      and i think this transition from track to track was not fluid, because memory in those days was rather pricey(memory to hold tv image in while tracks are being changed...)
      dunno if they could sync it to vertical blanking, so that tracks change only when electron beam is going from bottom to top ie when there's no image anyway...
      i doubt they were advanced enough to do that.

        Unfortunately DEFECT - it takes no more tape
        and makes loud mechanical noise when you turn on.
        only to spare!

        Reception part okay!
        Remote okay! (without batteries)
        including original user Bulletin

        Private auction - no guarantee - no withdrawal
        should be fixable... sounds like a stuck tape or blocked eject mechanics...

          Re: Frako caps in Grundig VS620 vcr

          @ i4004: pal tv sets of the era used piezoelectric delay lines to join even and odd scanlines in pal signals (for a less interlaced picture, I think) and secam tvs used them to store colors too, so memory was available. I don't know if it was cheap enough for a widespread use.

          @ Scenic: "loud mechanical noise"? It may be everything, from a blocked pinch roller to a jammed piece: inside pictures would be useful ...

            Re: Frako caps in Grundig VS620 vcr

            this vcr even has 'dynamic' tracking, so to speak. when it detects too much noise, tracking kicks in again! very usefull for my tapes!
            i thought no vcr has that.

            i dunno if delay line was enough...haeds were moved with stepper motor.
            it all kinda sounds too clunky...

            as for ebay machine, i would buy it, but it seems it's germany only.
            i would even pay scenic all expenses(7€ to get it, and postage to croatia) if he would be willing to ship it to me...

            i think i'll offer the owner option to convert his tapes to dvds and buy him some cheap dvd-player...at their place it'll be kinda wasted anyway.

            loud mech. noise when you turn it on? probably cassette loading mechanism jammed in some way. and probably something broken.
            still, i would give it a try because i really like it: picture on this one is rock stable, drop-outs are compensated, image is sharper than either panasonic or sanyo i have...

              Re: Frako caps in Grundig VS620 vcr

              i missed that auction..
              anyways.. i've sent a PM to the seller...
              he said he will put it on ebay again in a few days.
              i'll try to get it then...

              and if you have some time to play around with it i'll send it to you.

              doesn't really matter how long this takes..

              dunno... maybe i'll take a look inside if i'm bored and try to find out where the "mechanical noise" is coming from.
              maybe i'm able to fix it... or maybe not.. we'll see

              but i'll definitively take a look at those frako caps.. i think they will be bulged like in your vcr..

              mhh.... i wonder where my old JVC vcr went..
              was a really cool piece of hardware... automatic tracking, noise filters, digital effects (PiP, multiple PiP (up to 8x), strobe effect, solarisation, negative, pixeled, ...)
              left it in my mums cellar when i moved out (i didn't even have a TV back then... only a TV Card in my PC)..

              when i got it back to rip some videos onto the PC it just didnt power up anymore... completely dead

              but i didnt do anything to it.. just put it into a towel (so no dust can get into it) and put it into my cellar somewhere...

              was an early 90s vcr.. i guess '92.. and *really* heavy... sandwiched circuit boards everywhere

                Re: Frako caps in Grundig VS620 vcr

                hmm.... i searched for pics on ebay & google... only thing i could find (without the model number as i cant remember it) was its remote control.. lol



                was quite cool.. you could type the date, time and channel into the remote when the vcr should record something (thats one reason for the LCD in it (among others)) and then just send it to the VCR instead of typing it in on the VCRs miniature-keypad with double-used buttons (short push -> function1 long push ->function2 and so on...)

                if you have a JVC TV you could also use this remote to control the TV set and *all* of its functions.. (including videotext and stuff like that)

                damn.. that vcr must've been expensive as hell o.O

                  no frakos in this one: panasonic, nichicon and rubycon is what i've found.
                  mostly pana.
                  http://picasaweb.google.hr/i4004b3/GrundigGv501#

                  this is one damn fine machine.

                  it's the old mech design with lots of parts: best vcr design would be the latest models(which are so simple it's silly) but with metal instead of all that plastic.
                  it's really not that different to cassette player mechanism, while older mechanicds are really intricate.

                  if/when you get it, i can make you some pix of it's mech(bottom perspective) to make it easier to troubleshoot...

                  also that jvc should be interesting: it's easier to troubleshoot dead machine(psu not working), than the one with minute issue in video amp..heh

                    I agree: the GV501 seems a mid-to-late '90s model from the round knob and the graphics but it has a lot of boards auch as an earlier unit. Does it have the fast autoreverse (the 180 min cassette rewinded in 90 or 60 seconds)?
                    BTW, I think Scenic idea of recapping Frakos was intended for mine, not for your vcr

                      Re: Frako caps in Grundig VS620 vcr

                      i think it has fast rewind....it's not plugged in now, but rewind was pretty speedy, so it's probbaly late 90s model.
                      or even early '00s?

                      i think owner said its 8 years old.

                      >BTW, I think Scenic idea of recapping Frakos was intended for mine, not for your vcr

                      perhaps you missed this

                        BTW: that guy didn't put the vcr back on ebay yet.
                        i'll send another pm to him...

                          Yes, fast rewind and not autoreverse
                          Maybe it's a late '90s: I haven't found any info about it.

                            hehe...

                            i better get one more external hdd(500gb) and cap as much as i can in next week or so.

                            although owner says it'll be available to me whenever i want it...

                            funny thing: i could of probably transfer all of my tapes by now if i wasn't thinking i'll be ale to do it slowly, as it was supposed to stay here...hihi

                              Use these spare days for capping all tapes you care, then give it back and edit your caps in the meanwhile. When you've finished with picture cleaning and mpeg conversions, then ask the Grundig again.
                              You may even consider buying a good VCR if you can find it and the price is reasonable: yesterday I saw a 6 heads Panasonic VCR in a shopping centre, unused but at least 3 years old. Price asked was 120 euro, no wonder nobody has bought it ...

                                i'll see if this guy
                                http://www.njuskalo.hr/oglas38954
                                http://www.njuskalo.hr/oglas40451
                                would be interested in sending them over to me, me trying them and then paying if they work for my tapes.
                                if not i would send them back to him.
                                (i don't think he has many requests for info on this, so perhaps he'll agree...)
                                i surely can't buy them blindly, as i dunno are they appropriate for my tapes...
                                these look like tanks...but are pretty old too...
                                some more data
                                http://www.hood.de/auction/30048961/...tg-spitze-.htm
                                it's 1989. model.

                                here's one broken, for scenic
                                http://cgi.ebay.at/ws/eBayISAPI.dll?...4894&indexURL=
                                hehe....
                                (oups..that one is sold)

                                issue with borrowing again is following;
                                how long period is acceptable?
                                also, i would like to do it slowly, not capping the whole day just to be able to cap more tapes in same period.


                                panasonic i have has 6 heads, i think(2 hifi, 2 sp/lp and 2 ep..or perhaps only 4, 2 video heads for all 3 speeds), but 2 head grunding is beating it.
                                number of heads don't really mean much.

                                i may consider buying a good vcr, but that excludes new vcrs!

                                  I don't know if he'll accept the deal: I think he should prove they're in working order, serviced and such because he asks a respectable amount of money (the Telefunken costs about 90 euro, the Grundig 120). Ask him if he can refund the purchase in case you find the vcr broken or too worn (especially heads): you lose shipping fees anyway.

                                  No info about the Telefunken.
                                  The Grundig VS 680 is from 1989: according to an unofficial pro-Grundig site, it was the top of the line so it's the big bro of my VS 620. The ebay auction you linked lists all tech data: it had dubbing capabilities with flying heads and such, but for capping good autotracking and image stability are a must. There isn't a bundled TBC, I hope autotracking is good enough.
                                  There are service manuals for both, but not freely downloadable

                                  I found a worn heads affair and a bad caps one for the Grundig: ask at least for detailed photos before buying.

                                    deal wasn't accepted.

                                    so the chances are 680 has same frako caps as yours, it seems.
                                    and telefunken wasn't turned on for 3 years, he says.
                                    i think i'm better off.

                                      neighbour's vcr
                                      http://picasaweb.google.hr/i4004b3/LGLV2766Vcr#
                                      year 2002
                                      and works good: less noise than grundig, "dynamic" auto tracking as grunding, and ok drop out compensator as in grundig.

                                      oh yeah, grundig wasn't really making these machines: it was making vcr and video2000 but not vhs.
                                      grundig is usually panasonic(most of the time) or philips inside.
                                      501 is philips, this

                                      (one ad i saw today for used machine...about 50€) is panasonic (PAN-15 chassis)
                                      ( )

                                      my panasonic is from 2003, so essentially by that time lg was making better machines than panasonic.

                                        Fine: I'd never bet LG VCRs were good.
                                        So you're looking for a LG like your neighbour's one, a Philips made Grundig since late Panasonic are troublesome or maybe an even better recorder: no idea about the real manifacturer of my old Grundig and the old 680 you saw, but I wouldn't be surprised to be Philips. Issues for old machines are worn heads: replacing capstans, pinch rollers and caps shouldn't be too difficult and components are cheap, but the VS680 video head costs about £35 alone on a british shop and replacing it requires extreme care.

                                          inspect this link i already gave

                                          your 620 is pan 14(panasonic) and so is 680.
                                          could you provide few pix of that mechanism?

                                          it seems grunding was only making the earliest models, vs-180->vs-385 ("gru" series)

                                          i guess heads quality differs from model to model and make.
                                          my sanyo has no problems and the beating those heads got is pretty incredible(when i remember eraly attempts on tape splicing, damaged tapes i've put in etc.)

                                          i dunno am i looking to buy any sort of vcr anymore, because if i can borrow at 2 places it essentially means i don't need to have one.
                                          my neighbour won't really mind if i hold lg for longer periods...it's not like it's used on a daily basis for recording something etc.
                                          most people use vcrs as players, and these days they also have dvds, pcs etc.

                                            For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                                            It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                                            Hello,

                                            First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                                            I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                                            I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                                            ...

                                            Hello!

                                            I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                                            The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                                            I have studied the board and...

                                            I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                                            I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...

                                            Good evening

                                            I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
                                            Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

                                            But I was also suprised about the bigger boys, which are 330µF 25V.
                                            Could it be they used 25V caps because they were cheaper / available at that time?...
