ok, I see them now
bias pot in series with R13
and offset pot inseries with R4

Yep, that's correct. But if you use MPSA42/92 you don't have to correct that mistake. 😉 😀

I use MPSA42/92 in post #114 😉

Yeah, That's right since he used the BC327/BC337 is not the same pin configuration of MPSA92/42.

Oops, it seems I've jumped over that post. I should read more carefully. 😱

It's a PA actually.

Noted Mr. Mile...

Will revise that and repost tomorrow.

Pots for bias and dc offset can be add 🙂

What about this?

 

[apexaudio]

What about this?

Only just two changes 🙂 and MPSA92 can be closer for thermal connect.

Track missing, and move MPSA92 case to case for thermal coupling.
