jokerman777 Posted November 5, 2022 Report Share Posted November 5, 2022 My ignorance but I'm curious what's the purpose of C14, C15 and R11 at the output of the power amp in this configuration? Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted November 6, 2022 Author Report Share Posted November 6, 2022 keeps any dc out of the transformers. even small amounts of dc would saturate the transformers real quick. mikhail used the same circuit on the square wave instead of using a servo. 1 1 Quote Link to comment Share on other sites More sharing options...
Skooby Posted January 27 Report Share Posted January 27 Thanks Dr. Gilmore, Got a pbc made from the schematic. Played around with R1=120-ohm to get a good-enough sinusoidal wave; adjusting R2 and R3 to 10K to get 76kHz wave. Hand-wounded trafo, not pretty but does the job... 1 Quote Link to comment Share on other sites More sharing options...
