Well, I just lost HV and now no raster. I'm getting about 600 volts at the 2nd anode connection. I was messing around with the H freq. adjustment and then looked up and a dark picture tube! I tried to "undo" the adjustment but that didn't help. There was no popping sound or anything.
If you have a scope check the osc. waveforms and frequency against sam's. A guick check to see if your osc is working close to right is to check the grid voltage at the H out tube.
