Per my previous post about the single 3-500z amplifier with the tube
structure failures.
This amp had extremly high operating anode voltage from the power supply.
If my memory is still intact* the output would go to 6KV
with variac control, well past any point I would push a 3-500z toward.
Also the first tube to take a vacation was a 3-400z which has more gain.

*intact memory: reference most bad habits of musicians and politicians.
