    TBOR caps on Monster AVS 2000 power conditioner

    I just bought a NOS (new old stock) power conditioner, manufactured in 2007. Literally factory sealed and unused. I unboxed it and tested it to make sure it works. Everything checked out. I popped the hood to take a look inside and saw it has about 17 TBOR caps rated to 105C, ranging from 10uf to 220uf. How crappy are these caps and should I just go ahead and replace them right away?

      I would recommend replacing them all with Japanese 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.

          TBOR (actually TWBOR) are crap; I had a D-Link router full of those and suffice to say, it did not work since half of them had vented or pushed up from the bung.

              Done - replaced all with Panasonic FM and a few FC.

              Also, they had two 12V regulators on one somewhat substantial heat sink. Still, it got so hot that I had to pull my hand away. I added two smaller ones that all together, nearly double the size of the original. So...what the hell were they thinking putting the cap bank RIGHT next to a blazing hot heat sink?

                  that's the work of satan's school of electronic design - i'v seen it a lot.
                  it's either very clever - and evil or very stupid.

                  what will happen is the heat will dry out the cap, but because caps look better when they are warm you wont realise anything is wrong until you power it down one day and let it cool.
                  then it wont work again.

                      I think a little of both unfortunately

                          I think it's called too much theory in school and not enough practical experience.

                              monster stuff is overpriced underperforming hyped up junk so this does not surprise me.

                                  Yep, I agree. But I got it for cheap and this one actually does what it claims. Basically it's an automatic variac.

                                      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:

                                      Heathkit IO-4205 Power Supply Caps
                                      by eryjus
                                      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."
                                      ...

                                      Identifying caps on an old Zoom 9000

                                      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...

                                      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?...
