Here's an update: What I thought was a vertical deflection issue was not. Somehow, the CRT had been rotated 90 degrees so the vertical was fine...the horizontal was the problem!

Replaced the horizontal amplifier and oscillator tubes but it had little effect. The trimmer cap screws for horizontal size and linearity were seized so I removed the trimmer from the bottom of the chassis, disassembled and cleaned it. When I applied power, this is what I got. Obviously a very long way to go but I have something that resembles a full deflection screen. The Littlefuse diodes came today. Does anyone have any info on how to install one to protect this rare working 3KP4?
