I’m letting go of a few things from from my collection, including this Hoffman A 300 vintage tube amplifier project. This old tube radio chassis has been stripped of the radio components, and is ready to convert into a killer guitar amp! Has the right voltage range for a 5C1 Octal Champ, either use the 6×5 rectifier or convert to diodes to raise the B+. Power and output transformers are there, and tube sockets. Needs your own circuit installed – and typical updates like new. Servicing, caps, desired mods/conversion, and tubes if you want different than stock.

I don’t have a power cord. REMEMBER THE MOPA WORKS IN CONJUNCTION WITH THE GB 4000 AND A PLASMA TUBE. BY ITSELF, IT IS USELESS.

I tested the unit the inputs work I cannot get the radio to work. I’m not sure if I need an antenna or what.

This was a state sale find from woodside California and was plugged in every thing worked. Now no power at all. Was upgraded to new cabinet 18.5 by 18.5 by 19. By a professional radio shop for the ladies husband in the 80s it looks beautiful. Just don’t enough knowledge to figure out why not powering up. When it was working prior. Has every thing in the one cabinet the tube amp and tuner all wired and mounted solid. Or can meet within 60 miles for a better price. Only to lower 48 states only.
