It’s a dual-channel amplifier, probably dividing the bass and the remainder of the audio signal as was common in electric organ circuits. It was last powered on a bench about 10-11 years ago. The AC cord has been cut, and there’s some light rust corrosion in spots. The transformers are good, no shorts; this is a very good conversion candidate, perhaps changing the 7868 sockets to host 7591s – that’s just one of several possible directions to take this vintage project! This unit weighs about 15.7 lbs. See our other listings for more vintage, electronics, audio, and radio stuff. Thank you for looking!
