It has a CRT dated 12/80 Chanel Master that checks good and strong. It is a CTC 15 model 14g908mv and I am looking for a Sams for it. Does anyone have an extra or a scan of the parts list and tube lay out?

One little tip (applicable to the CTC-15, 16, 17 and 25 chasses)-- the two ground stakes on the far right end of the chroma board can go open-ground, killing the heater voltage on the two 6GU7s. Their plates go high, driving the CRT G1s positive, causing beam current to avalanche, which can quickly kill the 3A3 and flyback. So always reflow those two grounds as a precaution.

The symptom of the 6GU7 heaters going out is - the raster will bloom badly while going out of focus and then fade out.
