Hi,
I recently got an Adcom GFA-5800 for $50. I've used it as a subwoofer amplifier in my surround system. Then a friend told me that he has bought a new McIntosh and installed it as the stereo amp in his system - and that he was so in love with the result.
A long time ago I was also into high end fidelity but not anymore because of no time... so i thought. Until I hooked up the 5800 as my stereo amp (like my friend with his McIntosh) - and I was blown away. I have not heard music that good since I was young.
I found some smaller problems, a broken fan, a blown resistor and repaired it.
Now I'm thinking about new capacitors... the hifi bug got me back
I would like to ask if someone can tell me which capacitors I should replace and where I can buy new ones or similar ones?
Every help is much appreciated.
PS: I do have the GFA-5800 service manual if needed.

Thanks for the hint.
Anyway... I would like to ask again if anyone has experience with replacing all the caps in a GFA-5800?
Muffed...
If it sounds good why do you want to be replacing parts? I have a 5800 amplifier also but nothing inside has been changed or altered. I wondered what speakers you are using. I am rather disappointed with my amplifier when connected to ML electrostatics. The high end is rolled off and the speakers sound like they are wrapped in heavy cloth a few times. Other amplifiers I have work well with the speakers and are rather impressive.

There are a pair of 1000uF/16V filter caps for the high-voltage supply that often go bad in these amps. I don't have a specific recommendation for a replacement, but get something high-endurance, 105C, and 25V.
The 47uF input caps are pretty generic. Replace with some kind of fancy "audio grade" capacitor if you like.
