I know this isn't what you are looking for but the flashtubes were the
most common problem.

Thanks for posting. Flashtube works but frequency dial pot varies
frequency very little to none. Ohmed pot out and it appears to work OK
one end to the other and tube checks OK. I don't want to unsolder
parts to check them one at a time so I guess I will try to sketch out
a schematic.

I worked on one 2-3 years ago that would flash but not at a fast rate.
It was the flash tube.

Hi,
I can mail you a xerox of the whole manual, for the cost of
postage. Email me: adouglas at gis.net
