I am using a piece of wire wrapped around pin 2 of the crt to attach my video output test lead to, and the negative test lead I'm attaching to the chassis.
I've also hooked up the generator to my living room tv's composite input and verified that the generator is in fact outputting a signal.

What about if you inject at pin# 7, the grid of the vid.out stage?

Is there some other way to verify that the crt is ok?

The jug appears to be OK if you're getting a decent raster and the brightness control works as it should.

Could the signal be too high or low coming out of my generator to give a full picture when connected directly to pin 2 of the crt?
|
Too low, maybe. Too high not likely at all.

Will there be a party when this is all over that every one is invited to?

I'll bring the beer.
