I bought a maco duster from a guy and am trying to get some information about it. It has 2 ge 2057 tubes in it. Seems 8950 is a direct replacement. What kind of drive does this amp require? What kind of output if the tubes are good? The key circuit is missing. Will it still work? I took the cover off but haven't done anything else. Haven't powered it up. Trying to get some information first.
Thanks
it looks like the key input would be for a 1/4" and there is nothing soldered to it on the inside. What is the "control" lead on the back of this for?
