    Any advice on a Rodek RA2150? Caps died

    I'm recapping this amp and I was wondering if I sould do anything to "update" it.

    I plan on doing all the caps, I have no schematic.

    I was thinking of these:
    https://www.digikey.ca/product-detai...1923-ND/589664
    https://www.digikey.ca/product-detai...1840-ND/589581


    And the small ones I'm not sure what series yet.

    Should I just stick with factory values on the big caps?


    Also the thermal insulation seems to be paper....not sure what to do there either.

    thanks

      Here are some better pictures.
      I think I got the leak before it got bad.

      I used ammonia and iso to clean it off

      I was gonna put anderson PP's on the power cords and seen this last night.
      I'm also going to replace the power leads and use wire glands.

          OK taking the lead spacing and height limit of the big caps, here's what I plan on getting to replace these:

              Correct.

              Looks like your original caps are Nichicon PF. A lot of the old low-ESR Nichicon series from that era tend to leak (PD, PE, PF, PR, PY, and PL.... but especially PR).

              Nichicon PW is a fine replacement. Unlike the older Nichicon low-ESR series, PW has proven itself in the field for many years now.

              HV is also good.
              As for SR and SV... never used them before, so I don't know. I imagine they are okay, though.
              Rubycon ZLQ is also excellent.

              In addition to those, Panasonic FC and Rubycon YXJ are also excellent low ESR series for both switching PSUs and amplifier use. United Chemicon KY and KYB are also fine.

                      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?...
