Hey-hey!!!,
I got forced into using a common TX for both the B+ and a DC filament supply. It is Schottky rectified and L-C, but there is still a little bit of buzz which matches the switching of the diodes. It is just at edge of perception, but knowing why it is there is bugging me.
Guess I'll put a dedicated TX under there and be done with it. this'll give me a few more options for other experiments. I am going to put .01 uF caps across each of the Schottky diodes and see if that helps first...
regards,
Douglas
