Thanks for the advice. I inspected the board today, and checked voltages as suggested. The chroma bandpass and burst sections seemed good, +/- 10% or so. (some voltages required the color killer control to be adjusted to be in spec)

However, on the 6JU8 color killer detect & chroma sync phase detect I found some low voltages, see attachment. Where it is labeled 50V or -50V I found about +/-3V and +/-9V

Any thoughts? I checked a bunch of resistors around this tube they all measured OK.
