I took a look at the schematic for the blue static convergence pot - bah! It's a special - 100 ohms, with a tap at 25 ohms. I doubt I will find one. However, the red, green and blue DC pots are identical electrically and are tied in parallel - tops, bottoms, and taps -so. if the red or green happen to be sitting at a different rotation compared to the blue, I could just interchage the wiper connections and avoid the bad spot.

Waiting for some mica caps to show up in the mail - any day now, hopefully tomorrow, so I can start work on the weekend.

To do:
Blue horizontal amplitude coil
Blue static pot
Silver mica caps
Find out why the luma freq response is only 2 MHz - the manual shows 3 Mhz
See if focus control can be centered better

I think this hobby is proof of the law of conservation of difficulty
