repairing capacitors

[priscared]

I have a p2200 and one of the power caps started leaking. So i thought ok, better replace it. $200!!!!!! i paid that much for the whole thing. ANyway anyone know how to stop a cap from leaking. ANy glue or tape or anything. I just hope not too much has got out. ANyone know what inside the cap?
Thanks

Replace it!

Who quoted you the price? What are the specs (value, voltage) on the cap? I bet there's a more reasonable alternative available.

i think its 2200 100v i found a replacement "i think" for 30 bucks
Thanks

If it's paired with another cap, replace both. My guess is that you can do better than $30. They run under $5US here.

let me rephrase. 22000uf! and its well over $100 to replace!!! Anyone want to buy a yamaha p2200. ill sell it for $200

are you sure it is 100 volts?

because digi-key has 22000uf panasonic at 63 volts for $14.

I would take it off your hands for sure except the shipping would cost more than the amp

I think in another thread priscared posted that the supply rails were 80V. If so 100V is going to be necessary!

I had a look at farnel, and they didn't even have any 100V 22,000uf, had 10,000 and 15,000 but they were expensive, $50 - $100Aus. I was thinking maybe you could replace with 2 X 10,000Uf, at the expense of a bit more ripple, but You will still be back up at the $100+ mark.

Has it got separate filter caps for each channel. If so maybe you should ditch the idea of fixing the bung channel, and use it as a sub amp.

Sounds like its going from bad to worse

I have sixteen 4,700uF 100 volt capactiors.... lol but I'm not willing to part with them as that would leave me with no caps for the amp I am building... I believe what I have are old stock... so they are probably abit old.. but still brand new... you should look around... cos I got these dirt cheap.. 6 of these per rail would bring you up to more uF than you had before... 8 per rail could only inprove things, but space could be a problem... 37,600uF...

I pored glue on them, lol, it seems to hold the stuff in. 22000uf per channel. I swapped them around cause it was the working channels cap that was screwing up. I think u might be right, use it as a sub amp. HOwever,
I have spent 212.50 on it originally
30 on a guy trying to fix it.
SO if i spent 100 on a new cap
then 70 for new outputs. THen maybe another 50 for everything else on the board.
THats $463 if it works, that wouldnt be to bad for 230w into each channel, if it worked.

SO if i were to replace with other caps of smaller size, how abouts do u wire them. In series or parralel. Im pretty sure there is no room to do this though. lol
CYA
THanks for you help
