Adcom GFA-565 Capacitor Replacement

I own two Adcom GFA-565 mono amps. One began to thump while in use, so I brought both to an authorized service center. Tech tells me that he is finding DC across speaker leads on both amps, and that oversize capacitors need replacing and that he thinks Adcom no longer makes them. I asked for alternatives, he said "they make great anchors". Is there a place I can obtain original or acceptable substitutes for the capacitors? THANKS!

“Come on, Paul, tsk, tsk. Lytics are fine”

I thought this was an “audiophile” forum ;-)

“Easy to diy -- BUT if in doubt, go to technician.”

The tech is telling him “boat anchors” remember? Best stay far away from that tech – sounds like a shady character.

“It has to be electrolytic for the main power supply caps”

Nope – I used motor run caps in power supplies and they are the bomb. For the adcom there prolly won’t be enough space to go this route though.

Have a look at the value (MF and voltage) and get any with same MF and same or higher voltage.

Get film caps rather than electrolytic ...
