Excuse me Michael ...
I have several RCA Series 700 mobiles and stations here on both
High-band and UHF - none of them have a single tube in them. I
also have the supporting factory issued Instruction Manuals

Guess again ... no tube / no transistorized inverter HV
supply either. You must be thinking of the RCA Super-Carfone
and Series 500 mobiles.
Would you like to visit ... and dig through my collection
of RCA issued factory Instruction Manuals?
I used to service those radios way back when ... and do
remember which is what.
