One more thing, Bob.

Since the plate impedances the 850A and 851 (I know not about the 852) are
designed for are 2000 to 4000 Ohms, it matters not at which plate voltage
you use them except for the fact that the 851 is designed to be operated
below 2000 VDC at 250 mA for SSB and CW.

So your statement appears to be specious at best and doesn't completely make
sense.
