I tried the set without the HV cap and it seems to work fine with out it...no more sizzling
I replaced the Vert & Horiz. tubes along with some more caps and the cathode resistor on the horiz. tube. It measured 150 ohm instead of 100. I got a full raster for about 2 hours then the width shrank about an inch on each side.
The raster had a black bar in the center like hum on the video. It went away when I pulled the RF amp. from the tuner. The SAMs shows a 6CB6 as the rf amp, but the TV had a 6AG5 instead. Are they interchangeable?..any idea which one is correct?
Thanks
