Is the voltage across the 1L6 filament monitored all during the good to bad and good again?
Is the B+ stable?
I have found the bias resistors around the 1L6 to move in value when this sort of fading occurs. The fix was to replace these resistors. Other resistors in thee filament string can also be moving around...GL... chas
