    In a pinch for some parts I head over to Fry's electronics but typically only for resistors. I also hit up Apache reclamation which has bins of NOS components. I found lots of tubes, resistors,...

    If it has that molex connector it needs to be removed and soldered straight to board. As I remember there was a service bulletin from Bugera about fixing that exact issue.

    Someone should really notify Fender about those schematic errors. Maybe they care enough to edit the schematics they have on their servers?

    Yeah I meant 10v on base of Q6. Still I think Enzo is right that Q5 is doing its job and that Q8 is behaving strange.

    Yeah I had pulled that thread up a few days ago and drew all the voltages out on a schematic. I wrote Q4 (61.3v) instead of 66v as the thread said. I kept wondering was why there is 500mv at the base...

    I literally just watched EEV blog video where he is giving away 6 meters. They'll go to schools or something of a charitable source.

    Good thing is that there is schematics for the dsp for the amp. It's a bit complex though. First thing is to check for +5vdc supply on the dsp board. Do you have a multimeter to check voltages on the...

    The bottom side of the board that has tube sockets is where you'll find those flyback diodes. CR4 & CR6 is what I see on the schematic. They run from plate to ground. Test them with a meter to see if...

    Yes I see now and had just stumbled onto this as well. Can we measure AC mv value using a DMM at the input of the amp to have a reading of the input value?

    Possibly 5mw is around 500mv RMS? Probably a good strong signal to pump through the amp, but I guess peak value alone might be why it got loud. Inject a known signal read the voltage points with a...
