Hi Bill. It is using an audio transformer on the output but its an ebay one of unknown impedance. The description said 1.3k:8r but I have my doubts how accurate that is. The radio runs fine after I quenched some initial oscillation with larger caps on the power rail of the audio amp, its just a little quieter than I suspect it should be with the correct transformer.
I told Chris that Dean and I had also had some early trouble with AF transformers of questionable specifications. But in any case his receiver was clearly inhaling very nicely.
Congratulations Chris. Welcome to the Hall of Fame!
