Neil, If I remember correctly it was the RCA 500 series that had the tube final in the brown strips, am I thinking correctly? It's been a while! I thought the 700 line was all transistor in a grey box. The 700 line was similar to the 1000 line with the 700 being lower power.

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.

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?
