EL84 NFB

[trem]

I built a 2xEL84 P-P amp. Pretty much a cat biased AC15.
I was wondering about a NFB circuit for this amp. I looked at Merlin's book, and maybe need to read it again with intent.....was kind of a struggle. Perhaps it is just a bit above my pay grade so to speak.
Are there any Amps/Schematics (that utilize NFB) for the AC15 type circuit I can borrow from.?
Thank You

The Laney VC15.
Or LC 15.

If you want to look at a hifi amp, you can readily find schematics for the Heathkit ea-2 or ea-3.

Just a thought.
Negative feedback will clean up the signal.
It will also lower the output amplitude.
Is that what you want?

It doesn’t get better than the AC15 output stage for guitar but if you insist on trying to improve perfection try your namesake the 6G9 Tremolux

Jazz -
I think that is what I am after. I do not play guitar. Waiting for a friend to play the amp and get his opinion on how it sounds.
Thanks

Dave -
Thanks for the schem link. Maybe that will help this lousy circuit.
