Another easy test is to use a neon bulb electrical testr and hold it close to the cap lead on the Horiz Out tube withthe set running. If it glows you have Horiz-Osc, and output functioning. The HV Rect tube gets it's filaments from the inductive pickup of the flyback.
If you have an oscilloscope, you could check waveforms at the control grid of the H-out tube, but never use a scope to check HV out.
Swapping paper caps in the horiz sectons may be your only recourse to find out if the set is worth fxing. Measure DC voltages around the osc tube .
Good Luck!!!
