Richard - Thanks. I have decided not to go any further with my 65. I'm not going to be using it every day, after all. It works and that is good enough.
I honestly do not feel that changing the audio interstage section from resistance coupling back to transformer coupling will make a difference other than possibly slightly louder audio. Changing the volume control in Model 65 varies the screen voltages of the two 24 RF tubes. This would have nothing to do with the audio section of the radio. If I were to change back to transformer coupling, however, I would purchase the P-T156 transformer from Antique Electronic Supply since it costs half as much as the Hammond.
I am, however, going to make an investment to make one of my F-10 speakers work again. I have managed to get the field coil out of the "pot" of one of the speakers and it will be going to Alabama for a rewind soon.
