- Notes
-
First three tubes must be shielded. Set has 3 coils: Preselector, Autooscilator and F. Intermedia. According tu the tube line up, the model is 1933 or younger. Early type superhet with one 77 acting as oscilator/mixer and another 77 acting as plate characteristic detector.
The schematic shows a 25Z5, not 25Z6 and therefore 1933 may be true.
