Had a little fun with the Zenith today.. I'll get pictures up here later. The first thing I tackled was documenting everything with pics, then carefully removing the chassis. One of two cord drives broke while I was looking it over, but I got that fixed already, and have the tuning mechanism running much freer already.
The radio has a date stamp under the chassis declaring 10 Jun 1954, so it is a later model. The OP tube is a 35C5, so the schematic I have is not necessarily correct (it lists 35B5).
All the valves seem to have good filaments, but there is a selection of makes, RCA, Ratheon, Philco and a lonely Zenith, suggesting some replacements have been made.
There are also a number of paper caps, and two black-beauty types, so there's a bit to go through. Should I stuff? The main PSU filter is 80,40,40,40 uF. Haven't decided on the path forward with that yet.
I spent a bit of time on the Bakelite case, and have that looking really nice already.
All good fun.

I don't hold with furniture that talks.
