I do believe I did replace the agc filtering cap. The horizontal lock has gotten progressively worse with now less than a quarter turn on both sides to lose sync.
Will probe around with a scope and make a bias box.

just for fun try this a quick and easy thing.
find the 68k resistor on the horz board, read the value, it should be very low prob in 10's of ohms since its connected across the horz adj coil. Once you have found that resistor, connect up one in parallel another 68kish will be fine. See if that has any effect on the horz hold control, you want that to be a lot broader of an adjustment. Just use some jumpers to hook it up, no need to break out the soldering iron or remove anything. Be careful when using jumpers, you don't want to short out anything.

this is generally the 1st thing I do if I think the sync is an issue.
Note this assume the osc is not the issue (can flop both ways) Note the use of tube socket extenders so work can be done from above with the set on. watch this to better understand the function of the sync separator. https://www.youtube.com/watch?v=Flg5LwBadHI
