Vintage Tube Amp

For sale is a McIntosh MC275 power amplifier that uses 6550, 12AU7, 12AX7, 12AZ7, and 12BH7A tubes. Only essential parts were changed to make sure the amplifier is working as it should. Aside from that, to my knowledge, it has many original capacitors and parts.

Powers up, Lights work, All Tubes Glow, Tuner works Great, Amp Plays but one channel is weaker and it Hums!
