Given it's age, they typically need electrolytic caps unless you have blown fuses on that channel. They should all be replaced on the driver boards.
McIntosh 2105 - no power from left outputs
[Full disclosure - total McIntosh / vintage gear noob here]
I'm having trouble with a recently purchased 2105, and after lots of trouble shooting, it appears the issue is no power/signal from the left outputs. Right outputs work fine, and I get right/left signal when using the headphone jack (other trouble shooting tests include testing different speakers and speaker wire, adjusting the connection to pre-amp). I’m testing with new B&W 625s, Adcom 565 pre and a CD player from my old system. All of those are working fine.
I've been referring to the 2105 manual throughout and attaching speaker wire to the "Com" and 8 ohms connections on both right and left. (B&Ws are 8 ohms) Anything else I can try before taking it to a repair shop (luckily there's a local guy who services McIntosh gear). Thanks for your ideas!
