This posts aims to get opinions about why solid-state audio amplifier circuits are almost invariably much more complex than valve/tube amplifier circuits.
One could think that, if a good tube circuit is just redone, susbtituting each tube by a transistor (common cathode by a common...
As this is a safety issue, and I'm not sure, I would like to ask instead of experimenting.
Most digital scopes state a maximum input voltage of 300 V RMS.
I want to make some quick measurements on a live tube amp circuit and its power supply, which may go a little bit over that...
