[ARC5] BC453 on 24V - screen voltage

[Hubert Miller]

My point is, I suspect you cannot linearly scale down the HFO plate voltage as the B+ supply line decreases. 
My experience is that it is quite difficult, for example, to build a regenerative receiver with a plate voltage
below something like 6 volts. 

Very interesting idea, that the HFO plate was maintained at low voltage to minimize frequency drift. That 
the % voltage change with B+ varying remains the same, while the absolute HFO delta Ep is less.
