[QUOTE="midnightg35x, post: 6184897, member: 608400"] I guess I haven't seen many amps with shorted transformers, but I don't deal with many high power (1kW+) amps, so I don't have any experience there. I know you deal with these amps 10^10 times more than me, so I'm just trying to figure out how the ground pin on the 494 would fry out instead of the drive pins on the 494 driving the transistors. It is just curiosity. I have no relation to the OP. Also never dealt with any IA amps before, but the TL494 (besides maybe a SG3525) is about as common of chip as you get in a SMPS [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] [/QUOTE]
