    30yr. old Tracon Caps (& others)

    well... thats what i found in my little brothers amplifier (Elektra Super 50)





















    well... i'm going to replace all caps. the big fat Tracon in the first and the last 3 pics was completely dead.

    look at those 2 short videos..

    well... the amp was still working, but the balance adjustmend was everything but useful, it fried the power lamp like.. 5 times (overvoltage), sometimes it mixed up the inputs (you selected "Tape 1", but you could hear what's coming into "Aux 1" in the background)..

    well.. hope i can get this beast back to life

    but anyways: what about the caps? were those Tracons and FDS thingys good or bad caps?

    and any suggestions what to replace them with? (I thought about Rubys..)

      While on the same subject will someone please tell me why that on older caps (like in the pics here) there is no vent pattern on the tops.

      Even though its clearly obvious that there is enough electrolyte to burst the can?

      I see this alot in capacitors from the late 70s through the 80s.
      Elements of the past and the future combining to make something not quite as good as either.

          A tip if not already known. If you have any scratchy/noisy controls place a small drop of 10/20 grade oil on the wipe arm/track inside the control it has worked every time for me. Also has worked well on noisy switches.

              Tracon are bad caps. I had to replace a bunch in my old clock radio.

                  I have just had to replace a Tracon 470uF 10V cap in a Roberts R900 radio. The capacitor had failed short-circuit.

                      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).

                      https://www.badcaps.net/filedata/fetch?id=3591772

                      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
                      by Paxman_Swede
                      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?...
