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.
