I kept waiting for that Stock(?) power supply to go down in flames!...
Also might have been he did not check the calibration on the B+ meter circuit that was only showing about 2500VDC(if that much) with no load...I kept wondering when the caps or diodes were going to go FIZZ, when he tried to dump 400w to her and get more than the 2500 PEP "HIS" meters were showing when driven with 200w+!!!!
Good Bye to that set of Eimac's...What a waste!
Not to mention the input circuit network coil and caps!
I would not trust that Jackson Ball drive for long either...Interesting he did not know what that was either, not to mention how he thought he fixed it by simply crimping down the outer shroud holding tabs?...I really question that "fix"!
Also the HI/LO B+ and ON/OFF buttons had been modified with an additional relay... (so not stock)...Most likely due to previous switch failure...an even those were mounted in there "cock eyed".
What a waste of a good amp...A little more GOOD work and that would have been a descent piece.
I just kept wondering why he never did show the inside of the power supply.
I am guessing there were some "things" there he did not want anyone to see on camera.
The bias circuit was not long for this world either abusing that on AM like he was.
Shame would have made a good piece of equipment if rebuilt by a Good Mechanic.
All the Best
