Re: 120W PP EL34 amplifier re-born.
Ehm, that's an idea Chris, but the LM317AHV datasheet says it should be able to handle 2.2A. I've also had the problem with the heaters warmed and running for a while. the fault occurred yesterday when the IP signal was increased, in amplitude that is.
That's what I thought PJL, I tried different valves , both different ECC83 and 2's, no difference
Attached are some oscillogram's of said fault.
Andy.
