Elgin 80M? 80B? TRF radio

The 6D6 and 6K7 tubes serve the same purpose. Only the basing is different. 43 is a 25A6. 6C6 would be 6J7. 25Z5 and 25Z6 are the same. Only basing is different on the above tubes. The ballast can be any number as long as it drops the proper filament voltage @ 300 ma.


:Hello All,
: This circuit is so common but I cannot find any service data for this model. It has the 6K7 instead of the 6D6 and the 55B2 ballast. It has a 43 output tube, 6C6 RF Amp and 25Z5. So, just 4 tubes and a ballast. It's a hot chassis set. There is a listing in Slusser (formerly Bunis) for an 80B. This might be the set I'm looking for the service data for. Any circuit with these tubes and ballast would probably be fine. I think this came up before and was found to be the same as a Silvertone.
