Yes indeed, but with virtually the same main chassis as a TV125.
The TV135R was a cheapened (i.e. for rental customers) version of the TV125, with a printed circuit receiver unit and a small, square PCB fitted in the top region of the RHS main chassis panel, with the PCL82 (sound), PCL85 (frame) and PCF80 (line Osc.) valves on it.
The TV135L was a TV125 chassis, with a "quick release" chassis mounting feature (providing quicker removal for servicing). |
SS IF as far as I can remember.

Yes, the TV135 (but not the R or L suffices) UHF and VHF tuners used Ge transistors, as did the IF panel. A PFL200 was used on the 405/625 IF panel as the video amp, with the other pentode (usually used as a sync separator) used as a black level correction device (as per a Mullard circuit design, IIRC), as the main chassis used the pentode section of a PCF80 as the sync separator (as per the TV125).
