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.

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

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

Tony.

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...

Default hmmm

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
