I have a Kent midget metal radio, it has 3 tubes, 1 50l6,1 35z5, and one other tube that has no markings,the sticker on it for modle and tube locations is gone, does any one know what model it could be? or have a schematic for it?

Hi,
Sams does not list a tube radio for Kent. Chances are strong you will have to trace out the socket connections, as there are a number of possible choices.

You did not state if the unidentified tube had an octal base, or was 7 pin miniature, or a 9 pin novar base. If octal, chances are that it might be a 12SA7, 12SJ7, 12SQ7 (most likely), 12SK7, to name a few.

Also, are there any germanium diodes present? If so, that changes a few of the likely candidates of tube.

The tube that is present- Have you tried fogging the glass? (breathing on it, or placing it in the freezer for a few minutes is usually enough) then looking for the number with a light source at a low angle to the glass. Some were numbered at the top of the envelope instead of the side.

Hi,
Your radio was really made by Norbitt-Sparks (Arvin ), The three tubes are 50L6,35Z5 and 25B8. It's the same as a Arvin model 402 just a different name maker on it. You can view the schematics in riders volume 11 or here at NA.
Take care
