Incidentally fixed bias, I've upgraded to a very bad idea, the anode current is not in the least stable, if I used the ECL 80, that would have to be considered....

PM hasn't come through (I know my PM's work as I've used them in past).

The ECL80 anode current should be pretty stable with fixed voltages. If it's not, it is quite likely that the valve is oscillating at an ultrasonic frequency! But 'scoping will find that.
