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><\/b><\/p>\n<p><b>I told Chris that Dean and I had also had some early trouble with AF transformers of questionable specifications.
