Color Lock

amalon1308,

For you color lock problem, try touching up the 3.58 mhz oscillator frequency: (from the RCA alignment procedure) ground the grid of the reactance tube, pin 9, v707A 6EA8. Adjust the plate coil (tied to pin 1 of same tube), L704 for a zero beat note as viewed on the screen (zero or very slow "roll" in the color sync). Make note of the # turns L704 is moved so you can put it back if need be. Remove the short from the grid of the reactance tube. If this does not improve you slow color lock at turn on, then you have some other component or tube issue which must be addressed.

Regards...
