Windsor, you discovered the fundamental truth we were always taught
in Navy "A" school. Always check the power supplies first.
And Don, bless his generous Aussie heart, is correct also: you're
not fixing the problem -- you're getting rid of the symptom. Always
assume the original circuit worked great at one time and fix the
problem so that the orignal circuit works great again.
We had a tech in the Dallas Service Center who "re-engineered" the
front end of a sampling system to get it to work. I couldn't believe
the supervisor didn't rain fire and brimstone on him, but I don't
think the supervisor knew about it. Maybe he got the sampler to
work, but I pity the technician who had to work on that thing the
next time!
Dean (and you're welcome for the CRT)
