Jim,
What do you suggest for the next trouble shooting step? Unplug the CRT? or?
Thanks,
If you have a HV-Probe, stick it on the Anode lead.
I don't know what the HV is suppose to be on that unit
how ever, the last one i looked at was aprox 12k.
I had to replace a trippler in old MIll Spec scope
made by Dumont years ago. i still have the scope at
it works nicely.. 60 Mhz..
I ended up making a new trippler using the old
case that was in there. because i too, left the
scope on for a couple of days and came back to
find the fuse blown out.
I used a dermal tool to remove all the old contents.
used some common HV diodes and got some caps together.
soldered them together on a predilled board with no
foil. laid it in the case, and used HV putty layers
at a time with a heat gun to fill the majority of it.
then top it off using silicone.
It works perfect..
What i did to test it, i disconnected the HV coil
lead going to the trippler. did a HV ac test from there.
