So if the Power Supply components are good (as I suspect they are) then one of the circuits is loading the -6.3v down.
I researched where the -6.3v and it goes to the boards listed below. The first thing I would do is to lift the -6.3v one at a time to each board until the until the voltage pops back to -6.3v:
A6 Video Amplifier Assy
A5 VTO
A4 Crystal Oscillator/Mixer
A3 Loop Amplifier/Crysatl Calibrator
A2 Divider/Divider Bypass
When you identify the board, I believe there is a good chance that is where the overall problem is.
