I'm now @1.27A Iq and coocking.
Vg M101 4-5 mV, M102 18-19 mV.
R116 decreased in value?
I said :
give me present gate voltages of M101 and M102 - both ref to output node,
meaning :
red probe to M101 gate, black probe to output, and
red probe to M102 gate, black probe to output
now you know the drill
if you want more, decrease R116
gate voltages are symmetrical enough, no need to touch level shifter resistor

Many thanks!
I'm not at the end of the Iq pot, so I could increase the Iq further without decreasing R116, but I think 1.6A is enough.

Next channel tomorrow. Or today, but I'm tired, the day started at 3:40... which is not good.
also very good 🤪my day ended after that, then started around noon
I found the Iq very stable overall—BUT—swift changes observed with 4 sides and popping the lid on and off....I see ZM has all his stuffs in the wind on his bench.... dunno if it matters...
naah
it is at least range above, regarding Iq stability, than we are used with majority of Pa's amps
he's really counting on temperature continuum (system temp equilibrium) as important factor for functionality of amp
take it as blessing of A Class amps - to paraphrase his words - A Class is allowing me to make simpler constructions, which can only be beneficial for sound

Both channels Set @1.6A (176 mV) and cooked 😍
Now some design work, until the ordered parts (fuse holder, mains inlet) arrive.
