In my CTC-4 article (http://antiqueradio.org/RCACTC-4ColorTelevision.htm ) you can read about various tests I performed around the color oscillator. It includes a procedure for bench testing your crystal, suggested by dtvmcdonald.

If you confirm that your crystal is a goner, shoot me a PM. I have a couple of spares lying around and I could donate one to the cause.
