Kitting up for the BBA-3 now...
I think I will first adjust offsets and harmonics on the two "halfs" in SE configuration and then repeat after changing to balanced.
Can anybody tell me the make of the flat trim pots that Papa uses?

Am I forbidden to attach a .GIF drawing here?
It uploaded fine, but never showed, so I deleted.

An automatic offset balance for BA2 front end...

Sorry Nelson
The first performance graph is a little confusing.
Are you saying that the performance of the front end has this distortion (eg driving a 50k load) or are you saying the entire circuit with follower output driving an 8 Ohm load has this distrortion?

Either way I think I will build a balanced version of this amp driving a circlotron (follower output), I designed a while back.

Bloody nice work by the way (as usual).
