Default Unknown American midget chassis

Hello All

Can anyone identify this two-valve American midget TRF? It came to me without valves but tracing the circuit makes a 25B8GT / 70L7GT combination likely, with a dial bulb in series with the heaters.

Searching the Radiomuseum comes up with the Arvin 40/40A and a Lafayette clone of the Arvin 40.

This chassis doesn't look like an Arvin to me. Is the label on the rear panel a clue? It says W.M.Co. is this a known US company?

best regards ... Stef

Warwick Manufacturing Corp.

Nostalgia Air have schematics for Warwick, I've not trawled through them though.

Many thanks. Looks like a likely candidate, I'll take a look through their list for Warwick.

Yes the models 9-220 onwards look like good candidates. They use a 12B8GT plus 32L7GT with an external line cord.

I can see them on the Radiomuseum now.

Best rgds. Stef.

I remember seeing that schematic, but I don't remember what brand name it was sold under. Warwick built many private label sets.
The latest models had the higher voltage valves and a standard mains cord, where the earlier models had the older lower voltage valves and the resistance mains cord.
It seems that a lot of them didn't survive, as I never seen one.
