back on it again. Had a weak video out tube, that helped with the brightness.
I was getting all kinds of RF interference, a close exam showed some breaks in the balun mounted on the tuner. got that fixed up then I lost color. I think it was just the color pot grounding on the chassis when it was in the tuner mount on the back of the chassis. Of course I broke the neon bulb while putzing around on the chroma chassis so I went ahead and replaced that. While I had the chassis out I replaced the broken thermistor (it was just being held in place with pressure on the leads) with a CL-90. I also checked the schematic, the hacked in resistor was two 3.3k WW in P where there should have been a 680ohm...oy.... anyway I did not have a 680 on hand so I went with a 830.
there are some .1 brown drops (1kv) in the vert circuit that I will keep an eye on. I did not have any sweep issues but one of them sits right up against the 6EF7 and looks discolored from the heat. I don't like to make too many "fixes" on a working set at one time, so I will try it again and see if the color is working again. If it does I will prob pull the chassis one last time to go ahead and replace those, as well as the .0082 in the feed back and the .001 2kv snubber on the primary of the vert out (its one of those paper in hard ceramic tube shell types).
