I would like to verify if the st-120 is properly assembled, the output stage(speaker terminal), if not the entire audio circuit, is not earth ground reference?
If correct, I should be able to take measurements using an earth ground referenced oscilloscope at the speaker terminals without fear of blowing up the amp or scope?
Input source = function generator
Output = 100 watt 8ohm dummy load
I'm at 99% on the statements above but that last 1% gives me the heebee-jeebees.
I have not probed the circuit to determine if this is true, yet. (Unplugged, of course)
I do not have a proper isolation transformer, thus my question.
