He had made this, going to try that. (10pF C4,C5 is better if 2nd successful IMHO).

Hi Salas, I failed to see a BJT+MOSFET Sziklai in the schemas, as claimed in post 3367. Do I miss something? Also, IMO, Q5 and Q6 makes a symmetrical voltage amplification stage or VAS.

The schemas look very close to mine, however. All the best to the experimenter.

I wrote sorry, I remembered wrong (#3370). I also wrote he made your amp sans just few details.

Ah. I see.

In a much earlier post I think LC warned you of the thermal dependency of the BF devices. Is this okay? Coz offset can go trolling in a funny way.

They were OK in the old amp, their negative tempco helped the input pair even. As for what will do in yours, I will know in due time.

Damn I'm THE slowest guy here, As LC said...

Nice and sharp job Cambe!

edit: Hi Cambe. Did you forget to mirror the artwork? The peeceebee looks like printed as-is, reversed . Well, won't be a problem if you flip all the parts and PS also, I think.
