Parasound hca-750 issues

Solid State | Audiokarma Home Audio Stereo Discussion Forums - audiokarma.org
Hello everyone,

I've been following this forum for several months now, but this is my first post. So far I have found help with most of my questions by searching the forum. I could use some help with a recent purchase though.

I recently purchased a clean second hand parasound hca-750. I plugged it in and immediately notice loud distortion through both channels. It remains constant when I remove the inputs. I removed the cover and found that all 4 of the large power caps were leaking. I believe the to be 6600uf 50v ulna caps. (At least that's what I read in another forum).

I'm rather new at repairing amplifiers but I am quite handy with a soldering iron. I know that capacitors have parameters other than capacitance and voltage but I'm not very familiar with them yet. Does anyone know of an appropriate cap to user as a replacement? I tried finding new caps identical to the original but they no longer manufactured. It seems that 6800uf 50v caps are quite common and would be acceptable in the 6600ufs place. I'm looking to spend $10 or less per cap and any specific recommendations would be great appreciated. A product number would be even better.

Thank you for your time and help.
