Frenchy, I have been setting the crt screen controls using a volt meter. The controls are turned up about 2/3 to 3/4 of the way to give me the 800+ volts at the CRT cap. However, it won't produce a horz line at all.

John, you are correct... there are a few resistors there at the service switch. I've checked those... but with them still wired in... and they gave perfect readings. I'm probably going to cut one end of each and check again... just in case those readings weren't a result of the circuit looping around thru another resistor close by.

I also checked the coil you mentioned. One side is supposed to read 7 ohms and the other 12 ohms... both sides checked good.

I've been going back and re-checking readings hoping that maybe I missed something the first time around.
