I was running mine off a 12V SLA which can kick a few amps out
Mains I’d kill myself in two minutes thus I will only use linear supplies I built myself there.
Most of my experiments were deriving typical linear and CRT circuit bias from 12V supplies so I could run home brew designs off grid (ie ground referenced -15v, +15v, 5v, 200v, +2kv, -2kv). Managed to destroy about about 25 quids worth of coil formers learning about oscillator stalling
