Re: 120W PP EL34 amplifier re-born.
Thanks Al, some good idea's there. It is a puzzler, it's almost as if something is being transmitted back to the ECC83 triode gain stage or the LTP IP has gone very low Z, which I discounted as everything works from the LTP on.
It's a pain this, it should be coming together not falling apart, that said I'll find the fault and it's honing my fault finding skills. I start by wildly unplugging things, then actually start to reason. Ho hum.
Andy.
