Re: Loss of focus on a Wells-Gardner XY...

Check for changes in voltages when it warms up... maybe HV, etc is
changing when it warms up.

I had the transistor mounted on the back of the HV cage on my
Space Duel work fine cold, but draw too much current when hot...
although generally my picture got bigger... not fuzzier... prior
to it blowing a transistor and zener diode on the hv board....
