I'm working on one also... likely had not been turned on since my parents moved out of the farm house in the mid 60s. Fuse resistor was open, so I stuck an 8 ohm resistor in there (was the orig 7.5 or 5.6?).... got a 5 inch high pix, somewhat unstable.

On the bench, I "j hooked" all the caps on the main board, cleaned all the tube pins and got a decent pix about 90% of full height. Watched it for a while, until the heaters went out. Heaters ohmed ok... hmmm there must be a series resistor somewhere.... spotted it and more caps on the back side of the chassis.

How did you get your chassis out? Did you pull with the CRT frame/CRT attached, or leave the CRT in the cabinet?

Mine is the common alligator skin style cabinet... fun set anyway.
