Thanks for chiming in so consistently. Very much appreciated.


Magnus, I've checked all the voltage on the horiz. board and it checks out fine. Here's the schematic with my measurements in yellow. https://groups.yahoo.com/neo/groups/TekScopes/photos/photostream/lightbox/1616728419?orderBy=mtime&sortOrder=desc&photoFilter=ALL#zax/1616728419 https://groups.yahoo.com/neo/groups/TekScopes/photos/photostream/lightbox/1616728419?orderBy=mtime&sortOrder=desc&photoFilter=ALL#zax/1616728419


David, I'm checking the HV board next especially the -3k point. I'm using a HV probe which I'd never used before. If it really is 150v then I could use my regular meter.
