Yes. Tubes all tubes are new, though the amp has sat for a long time and there could be corrosion in the sockets. I could check that but here and now I'm exploring options for jettisoning the PCB board.
BTW, found some informative videos on YouTube:
The transformers in my chassis have identifying marks but they are mostly illegible - rusted over or never stamped clearly in the first place. Can a tech test these to find their specifications, or is that even necessary? I'm wondering if, since these are both EL34 50-watt amps, might it be safe to just swap the PCB board out for the hand-wired Marshall replica board and just roll with it? The Marshall board I would use would be a replica for a 2204 Marshall. Both amps have similar controls (Master, Gain, Bass, Mid, Treble, Presence, separate Power and Bypass switches, two Inputs, . I'd have to go without reverb, however. I'm just getting started in trying to figure this out.
