With a lot more bench time than I've had in a while due to covid19 lockdowns I finally got back to this.
So far I have replaced some off tolerance resistors in the IF and color stages and managed to coax a decent color picture out of it.... however it don't want to stay good. The color osc is drifty and looses lock occasionally....more frustrating is the tendency of the osc to jump between being locked on the correct phase of color burst and the inverse phase...I can sometimes get it to jump between the two by adjusting horizontal hold... Which is not wonderfully stable either.
