Philco Bristol update
#6

A small update dealing with trying to find the cause of lack of screen width on the right side. I've confirmed values of components I installed restoring the sweep board. A couple things I noticed... I failed to replace 2 silver mica caps in the 6CG7 horizontal oscillator circuit. My brain thought they were ceramic disc. I probably should change them. Also I missed the resistor at the base of the H.V. rectifier tube, and it reads high, so that will get replaced. I'll also replace the resistor at the horizontal width switch as it is original as well. And MrFix55, there is no capacitor at the yoke however there are two resistors. I suppose I should check these. My thought process is that not filling the right side of the screen can be caused by the horizontal output tube, or circuit. New tube did nothing, so it,s off to the circuit. I'm also planning on running the chassis on the bench with yoke hooked up and H.V. lead in a glass jar. It'll make voltage checks easier
