First time post. Just got my first Sansui, a 3500, not the G series. Cannot find much about it, but it came with a full schematic and I found a service manual pdf. I started it up on dim bulb, was fine, checked dc OK. Opened it up and found one of the right side output board had been re capped. I have not worked on receivers before but has built and repaired boards before, mainly power and switching boards. I am planning to re cap the left channel so they match, replace zener diode and oil caps, Is there anything that I need to look at that? Any known problems in a Sansui? Looking for Help here, Thank You in advance!
