I "fired up" the 4 on Sat 2/17, and I am attempting to attach a couple of screen shots. The color won't sync, and only preliminary adjustments have been made, but it did not smoke, and the 6CB5 is not glowing red.
I used a 21AX that tested very good on a borrowed RCA crt tester. I guess mine is giving false readings. More info to follow as the work continues.
