60's color motorola

You dont need to change or clean the controls in the back. First of all you should be able to get a completely clear B&W picture with a properly connected VCR. There should be no snow. You may need to check or just change the RF amp tube in the tuner or maybe a bad balun. I would also check the IF tubes in the set as well. The fine tunning control will also impact the snow on the screen. Get a good clear B&W picture first. Then worry about the color. You likely have no burst or the chroma oscillator is not working. There is a color indicator light on the front between the color and hue controls on the front. Does it come on while playing the tape. If you cant get it to come on then look at the Burst amp and Chroma Bandpass amplifier circuits. If it comes on but you still have no color the refrence oscillator may not be running. Don't worry about things like demodulator tubes and color set up or convergence yet. That 6gh8 tube may very well be bad and will cause no color. I would bet there are some bad caps in the color circuits as well. On the plus side it looks like you have a good 23EGP22 CRT. That is a plus in itself. You have high voltage, and the horizontal and vertical circuits are working. Looks like a pretty good start and a nice cabinet as well.
