    Amiga CD-TV caps questions

    Hello there!

    1. question:

    I'am recapping my Amiga CD TV (great machine)
    The old caps are all 85 deg. I have found 105 deg. repleacements for the all,
    except three 4.7 mf/25v caps. I can only find 85 deg. for this voltage.
    But.. I can find 4.7 mf/50v at 105 deg.
    So, is it ok to up it all the way to 50v ??

    I have checked the voltage of the three caps and two are on 3.84v and one
    on 5.2v.

    2. question:

    In the power supply, I got a 120 mf/400v cap. is it ok to up it to 150mf/400v ?

    Thanks!

      50V units are fine, considering that they are about the same size or smaller (I have found that the 50V units are available in more low capacitance values from 0.1uF to 10uF compared to most other voltage ranges)

      Provided that the replacement is the same size or smaller, it should be OK.
      If it is a snap-in unit, only replace it with a snap-in unit. The same applies for radial lead units.
      My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

          Thanks for the help japlytic!

          The sizes are the same, so no pb

              Mind posting a few shots of your CD-TV? It looks like an interesting machine.

                  Its my pleasure

                  I only have a camera-phone, so pics are not so good, sorry.
                  This is pics of my spare unit, the other one is disassembled for re-capping.
                  Most of the caps are "SHOEI", I've seen them in a lot of Commodore computers. It can't be that bad a brand, these caps are still working in units
                  from as early as 1988!

                      SHOEI, that sounds very familiar for some reason.

                      Anyhow, that is one sleek looking machine. Kind of like an early HTPC... but in 1990! Ahead of its time just like the Dreamcast.

                      Be sure to let us know how the recap goes.

                          Sure.
                          The caps should arrive today from RS Components.

                              Recap is done, and the machine has been on for two hours now.
                              Just need to fix some loose leeds for the joystick expansion.

                                  Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                                  by momaka
                                  I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                                  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!

                                  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...

                                  Help with switching power supply caps
                                  by captain150
                                  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,...

                                  Gigabyte GA-6OXT :: caps question
                                  by Foetuss
                                  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?...

                                  EVGA e-GeForce 7600 GS AGP 256MD2 [256-A8-N542-T2] with bad caps - fixed
                                  by momaka
                                  I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)

                                  So, here is the...
