Westinghouse K840CK15 Restoration

[trinescope]

I know these can't be run all that bright and that's fine with me. Pretty much every picture of an operating 15GP22 set does have that distinctive yellow color bar, including my own set. I'm sure mine is in need of tweaking and I hope I can get a proper color bar signal to use when the time comes. There is an adjustment procedure from Westinghouse when a color bar signal is not available that should get close, but it involves injecting a signal into the video path at some point, which may need to be done with the CRT off the chassis.
