Second attempt was better 2:1 ratio this time which was reflected in voltage and CT voltages. 11.36v Primary : 5.31v secondary CT 2.62v and 2.62v. From what I've read about this audio circuit , it was used in a few different radios. Some with 35ohm speakers and some with 8 ohm speakers. All the documents people show (me included) show a 35ohm speaker, but that actual Deacy Amp has two 16 ohm speakers in parallel giving 8 ohms. So we can safely assume dont wind a 35 ohm transformer coil for the speaker unless you want smoke. I'll wind my audio output transformer soon and see how it goes. Not sure how the newer germanium transistors will go.
