Update on my Admiral. I fired up the set last night after replacing another 10 resistors (have done about 30 so far) and the noise pulses (horiz. line flickering on the pic) was really bad. So with the set running, I tuned off all the lights and tilted up the set looking for arching - could not see anything. I turned the audio all the was down and could hear a very faint buzzing. The buzzing was a pulsing buzzing that seemed to correspond to the blanking. Sounding just like arching, but I could not see any arching. Seemed like it was coming from the area of the Horiz. sweep transformer, or between that and the 6kV caps. Then I saw the long red wire coming out of that transformer and wrapping around two of the 6kV caps. I took a plastic screwdriver and got that wire away from those 6kV caps and the buzzing sound and blanking stopped immediately. Re-routed the wire away from those caps and solved that issue. Now onto the vertical to see if I can solve the linearity issue, which has improved, but bottom of pic is still squashed. Here is a new video of where I am . . .
