I have a PS900 Oscilloscope from about 1972 that doesn't have a working horizontal sweep. I have found a schematic and wiring diagram, but don't understand it fully. I think the issue is in the sweep generator circuit, probably where the frequency is generated. Everything else seems to work fine other than the CRT shutting off after a few seconds sometimes. If anyone understands this better than I do, please help.
Here is where I found the schematic and wiring diagram: https://bama.edebris.com/manuals/vudata/ps900/
If there is a link on PS900, it is not intended.
