Re: 120W PP EL34 amplifier re-born.
"I reckon Chris has it, foldback limiting." It has to be it DC, however the I max of a LM317AHV is 2.2A, see attached "Does that fit with reality" With a 5ohm load, it goes into current limiting mode.
My winding is beefy enough 16AWG = good for 3.7A less a bit @ - 10v (13.4v), I'm using a 2200u reservoir cap.
In the end I used a TIP3055 as series pass Q, no more issue's.
Andy.
