Thanks GJ, for posting Keith Snook's diagram. He clearly expects the KT66's to draw their full wollop of 65mA. My knowledge of Quads is just about nil, but I can see & understand that the amp specialists here have concerns about imbalance.
How old is peterp1's Amp I wonder ? Still no info yet on the "electronics man's" Valve Tester or proper Ia & mA/V results at the Book's value for Vg ?

Regards, David
