Zenith 29JC20 restore

I have restored sets before and know the usual procedures and risks for the hardware. Assessing the task. The CRT is SO DONE and will be replaced. Purity ring assembly disintegrated and convergeng cloverleaf cracked. I slowly brought up the set fillaments only and all was well, brought up with HOT cap off still all is well. Brought up HOT cap on and in a dim room we have sweep and raster. With a signal there is a picture but the vert hold range is at the limit. and very poor horiz lock. Phase 1 is to repair any reasonable issues to restore proper operation. Are there any 'Known" issues with the sync for this beast? Phase 2 is to replace paper caps and black beauties and verify operation along the way. Also checking resistors as suspected or needed. Phase 3 adjust and setup.

This chassis is quite clean under the dust. It does give the impresion of being a high mileage set in a clean environment. Signal tubes are original, sweep tubes are not. No supprise there. There is no degausing coil in the set, that was a supprise.

What should I know about quirky faults for this chassis and why would be a splash of yellow paint on the power transformer?
