How do the DC voltages on the horiz oscillator plate, grid and screen, and the horiz output tube screen voltage compare to the schematic? How are all of the voltages from the power supply section?
Have all the capacitors been replaced in the set? It sounds like a power supply/DC voltage issue.
Could even perhaps be a boost voltage issue...the horiz output tube starts up on just B+ but then runs on boost after the set is fully warmed up. If I read the schematic correctly, the caps which develop the boost voltage are drawn in right under the flyback.
Also what else connects to the damper fuse? There appears to be something else which apparently uses boost voltage and may be dragging it down if shorted or leaky.
