What is this 2 tube TRF receiver

6/17/2010 8:05:43 PMBruce Walters

I bought this two tube TRF set a couple of years ago and I finally decided to see if I can make it work. First I would like to figure out what it is. It appears to be facotry made because the small cabinet is built with machine done tongue and groove joints and the fron panel is definately factory made. Yes, it could be a kit also. It has two tubes, one of which is a 201A (good tube) and the second is not marked, but could be a non-functional 201A or just not a 201 at all. The characteristics are: 2 tubes (may not even be the correct tubes currently in the radio), 1 tuning dial, 2 connectors on the left front (antenna and ground?), 4 jacks for speaker or ear phones on the right side. 3 additional knobs, two are the old wire wound pots and I can't tell what the third one is. The most distinguishing characyeristic is the cross on the front of the cabinet, made from 5 counter sunk holes up and down, and three across. I know it's a long shot, but if you know what this is, I sure would appreciate the help. Or maybe you can send me a schamatic that represents a typical two tube A,B,C battery type set.

Thanks

Crosley 51 is a two tube radio but not what you have. Crosley used a book cap for tuning but circuit should be similar.

:Thanks Norm, I will check it out. I am most concerned about where the C+ and C- leads connect on the receiver end, they were disconnected from the radio when I bought it and I am guessing where they go. This is probably give me the clue I need.
