Some information please
#16

Yes I agree. There seem to be a lot of non-stock modifications, regardless of what the radio started life as. I would be afraid to plug it in until you traced out all the AC wiring and confirmed the chassis is isolated and not in any way connected to the AC line conductors.

The power supply looks a bit suspect. There seems to be a type 81 half wave rectifier installed which does not look original, especially after you mentioned the cabinet had to routed out to make it fit. More likely a radio like that would have used a full wave type 80 rectifier. There also appears to have a ballast tube next to the rectifier which does not make much sense in a transformer powered AC radio.

Other than that, the original radio seems to be a usual late 1920's AC set with type 26 RF amps, a 27 detector and push pull 71A outputs.
