color bars showing lack of tint shift.

the plan next will be

exchange color output tubes just so see if there is any change, sub a new demod tube (uses a single dual triode for the X and Z) again just to see if any changes.

if no improvement, I will pull the chassis out some so I can get to the test points. The sams has me grounding the output from the chrroma band pass trans (not sure why, this is point N on the sams) then puttting a vtvm on one of the pins of the 6AL5 phase detecting diode and adjusting the 3.58mhz osc coil for max deflection, then adj the burst trans again for max deflection, lastly grounding point O (the ref voltage from the two matched resistors) and setting the reactance coil for color bars that are still or nearly still. (of course this is with the tint control set to the middle of the range) I have not done the max deflection setup part before so I will measure the coil settings before adj JIC I need to get back to where I am now.
