I have connected again the EI core 240V, I have to wait the warm up to measure current in the reg. I will come back later.

290V is no problem for the phono if it will help freeing your Vin-Vout margins. Bias is still in spec.

Connected again waiting warm up to adjust reg to 290V to measure input voltage & current at the reg.

It can go up to IDSS Q2 when degenerated with 10R is the exact roof in each sample.

Use only the one DMM, just on TP.

True RMS is for DMMs evaluating correctly the RMS value of non sinusoidal AC. Its DCV range we should use on TP. You could fix your current lower than max allowable before? Is that trimmer OK changing value if tested with ohm meter when power is off?
