Real Dirty Pictures

My much beloved CA2010 of thirty plus years needs cleaning, has drop outs, and now has a horrible static (loud) which made me quickly take it out of commission. I have failed at deoxit cleaning rituals, having attempted three times to clean the volume pot and other switches mentioned on this board. I've seen a little improvement, but not much Symptoms: Slightest vibration to the amp would cause both L and R channels to cut in and out and/or distort ,crackle,pop and hiss .. right channel more than left. Fix...Primary - The "Mode" switch.. secondary- the protect relay contacts.. Had to disassemble the mode switch to thoroughly clean the contacts.The switch was saturated with deox-it but the contacts were so badly tarnished that the deoxit wasn't doing diddly..After cleaning the switch contacts and reassembling/reinstalling the switch. The crackling and hissing and vibration sensitivity were no longer and issue. But the right channel was not engaging until you cranked open the volume a little ..relay.. Replaced the relay..Totally recapped the amplifier ,adjusted DC offset and AB/A bias..We are Rock'n and Roll'n now without any hiccups or issues...:music:

Ah, I see, thanks for explaining.
Ever used or assessed this output on an A1?
If so, did it sound good or... not so good?
