Re: 475 questions


Thanks, Dave!

I'm surprised that I would find AC voltage at the rectifier filter caps. I thought those came after the rectifier in the circuit, so any AC would be gone by that point. And if the rectifier IS shorted, THEN I would expect to see AC at the caps. Clearly, I have much more to learn about power supply circuitry.

I will try these tests and see what I find.

Thanks for your help!
