I presume you mean the 12AZ7 dual triode (ref osc goes to K's chroma info to grids), I have not, but will. Something else that was odd that I did not notice before is I have red screen background (there are RGB bkg pots adj G1 and GB scr pot on G2 which is a little different than I have seen on later models) has to be set to the min for the grey scale to work the G and B are not at min, nvr had a CRT where the red was the strongest gun. So the G2 red runs wide open and you adj the G1 red with a pot.

I prob should check the kine pins for voltages to make sure all is well there.

what makes you think there is a demod problem? seems to me the colors are correct just lacking in phase shift of the ref osc.
