I finally got all of Allards updates in....when I was finished I noticed that the audio output from the speaker was garbled and sounded off frequency. Changed speakers ( all 8 ohm units) no help....hummm.
So I suspected that 47 ohm resistor in series with the speaker or the sidetone wiring.....dropped that 47 ohm resistor to 22 ohms and all is well....got the volume back and nice audio...
all fixed....except I blew the IRF510 out.....
no "good fix" goes unpunished
