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 |

Re: Unknown American midget chassis
Many thanks. Looks like a likely candidate, I'll take a look through their list for Warwick.

Re: Unknown American midget chassis
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. |

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.  Dave, USradcoll1 |
