Hey, I have a colleague who has fixed these, their advice is: “Check the fuse for the EHT power supply first. It’s located on the main PCB, close to the middle. If this fuse blows, no EHT, and no trace. I fixed a Q1803 ‘scope a few years back by replacing the fuse for the EHT supply. There were no other faults. The symptom was no trace.” :-+ |
