Well the results are in! Again, many thanks for your help.
With the plate cap of the high voltage rectifier disconnected, I got a nice arc off of it (about 3/4 - 1 inch) with a grounded screwdriver. I was a little leery of doing this because the set in this production run does not have a 1/4 amp fuse protection for the flyback. I did some resistance checking with the rectifier removed and found that between pins 7 & 4 (across the 3.3 ohm resistor) its 3.5 ohms, but I was using an empty tube socket adapter and had to really wiggle it around to get that - otherwise the resistance was higher (38 ohms). So something is up with the socket. Between pins 2 & 6 its 980k (across 1M resistor) and between pins 2 & 4 (winding in flyback) its 0.1 ohm. I did some resistance checking from the pins of the socket to ground and found that there is 12M resistance between pins 2,4,6 and 7 and ground. Is this normal? I want to rebuild this area this weekend, but all I have are 3 watt metal film resistors. Will metal film be OK?
