Your request for info on that part made me look at the parts list I have had for close to 20 years. I don't think I ever used it for capacitor info as it was always available on the capacitor. I see my information (provided by another ham) isn't accurate on some of the caps. It is also possible the info was correct for the P.S. he had, as Yaesu changed many things on the 736 and didn't document them all.

Looks like I can't totally trust the parts list....sorry

Hi Richard, No problem. C24 isn't ceramic. I've been studying the components on that side of the schematic to see what other component could have failed to cause the SCR to blow. If C24 got hot and shorted, I wonder if that could have done it.

The 736 is in fine shape, I hooked it to an external supply and current draw was normal. The bad part of all this is that my eyesight is not as good as it was 25 years ago. :-)
