Where is that Genius when I need him? Problem is that their is 1 duty cycle sine wave between square wave duty cycles at pin #3 input of transformer TX3401 Primary side. Square wave is at the right frequency. For the life of me I cant see where its coming from, or how its being generated. Does not seem to be a component failure.No print and no more Ideas. Only part not checked and or subbed is TX3401. Rick Mitchell Mitch's Electronics Ser.Co.
