Crosley 1949 - Horizontal Linearity Issue

[SteveMartin]

Working on a 1949 Crosley model 9-407M-1 (12” 1949). I’ve got a picture, but the horizontal linearity is poor and I can't adjust it out (see CRT pic). All the tubes test good, fully recapped and I’ve replaced several out-of-spec resistors in the horizontal circuit. I’ve attached the schematic of the circuit and the scope traces I’m getting at various points. The tube & pin numbers are labeled above the waveform. I don’t have a lot of experience looking at the horizontal sweep signals so I’m not sure what to expect. I was expecting to see a sawtooth at the damper tube (V23 pin 4-6). Instead, this signal seems to have a lot of ringing and an extremely fast rise. I’m hoping someone can help me isolate where the horizontal drive signal is going bad. I had many more scope traces from different tubes/pins but am limited to upload only 6. If there are any other probe points I should post, let me know. The schematic is an attached file to maintain reasonable resolution. All ideas are greatly appreciated.
