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. :-)
