There is no cap on the screen/focus block......the previous tech was dincking around inside, maybe using the cap for some weird test.....none that I can think of tho'. Hey Jim....who was that guy back in '91 that used caps to bypass questionable circuits....he bridged over a circuit with the cap until he got a good POW!! out of it, then ordered parts. KEN??? Na, he was the guy at PKW...we didn't have PKW at that time....he was hired same day as I was.
