Help to ID this chassis and valves
Hi folks,
Picked up a Gulbransen desk-top radio-gram but it's missing the ID info off the back. Also missing two tubes, which so far I believe are a type 80 rectifier and possibly a 2A5 output. I'd like to ID the chassis so I can find a diagram for it and work out what the tube complement is, as only one has a number on it (the others have worn off) and that's the one in the centre at the rear which is a type 85. |

Re: Help to ID this chassis and valves
If one of the tubes is an 85 then the radio must run on 6.3 volt tubes, so i would expect the output to be a 42 with an 80 rectifier. The others could be 6A7 convertor and possibly a 78 or 6D6 IF amp. Most of the schematics for these are all very similar.
