Actually I was wondering if the original 150mA was a good design point in the first place and if it should be increased to say 200mA. I didn't know if there were some good rules of thumb for the worst case draw for these output tubes.
I also got some more info from Ashdown as they have provided the DC voltages in the power supply:
CT 355 v + /- 10v.
G2 345v +/- 10v.
HT1 240v +/- 10v.
HT2 210v +/- 5v.
HT3 200v +/- 5v.
A1 215v +/- 5v.
TP1 ( BIAS ) 10v +/- 0.3v.
