I've tried all your suggestions. But for this last one ...there is a problem.
That is, there are big blanking pulses on both cathode and grid. This means that the voltages measured on a voltmeter are not necessarily representative of
what they are during the active scan time.

I will retry this evening with the two blanking pulses disabled. And I will
look at the two pulses with a scope and see if they drift.
