    Carvin PA620 - Need help finding replacment caps

    The amp we use to play music in auto shop at school crapped out the other day. It works but there is a loud arcing sound when you turn it on, and there is buzzing in the output after about 5 minutes of operation. The auto teacher and I are buddies, so he asked me if I could take a look at it for him. I brought it home and opened it up. BADCAPS!! They smell like shit and all splooged out the bottom. Sadly, this amplifier is Made In USA. Too bad the caps aren't!!!

    Here's all the cap values - can you guys help me figure out what series Panasonic caps I should replace them with? All the caps have the Carvin name on them and are marked 105C. There is no series denotation.

    4700uf 50v x2
    1000uf 25v x6

    Would Panny FC work?

    Hey guys. Had to get the order in about half an hour ago, so I ended up going with Panny FC for the 1000uf caps and Nichicon VZ (105c) for the 4700uf caps.

      FC are probably okay but with original specs can't say for sure.
      I'd use Panny FM just to be covered.

        Caps came in. The install went without issue with my new 40w station I just got. The amplifier came up beautifully and sounds better than before (bass seems to have more of a punch to it). Those Panny FCs look sexy compared to the crappy old caps that were in there. Interesting observation: the new Pannys (exact same uf and voltage) were the same diameter as the old caps, but almost twice the height. Anyway, I'm glad to see this amp running properly again. Its a very nice, sturdy amplifier and the build quality is very good sans the caps. Hopefully it will still be bumping tunes down in auto long after I leave High School.

          The original caps were probably over-rated.

          I worked on a Carvin amp not too long ago for my girlfriend's brother, just replacing some worn out 1/4" jacks. I was not too impressed with the build quality, there was a good reason why the jacks broke. The amp was relatively new. While I was in there, I noticed a bunch of CrapXon caps... he didn't want me to replace them, but I told him he knows where to find me when he runs into problems again

            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
            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?...
