I've just come back from hospital. Atrial fibrillation. Got fixed but still recovery will take some time. I see that Alex did quite good job. I'll try to check pcb consistency with the circuit diagram over weekend. At least I'll do random check of various parts. If I discover any discrepancies I'll report these. Has anyone found any layout errors?

cheers,

Default LT Spice

I did not find any errors but I only checked randomly selected sections.
I do not know if you did here LT spice analysis. I have created two versions of this amp: single Miller and two pole compensation. Changed a few component values to get smaller distortion.

How things are going with pcb design?

cheers,
