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

They're similar, but not exactly the same. The 6AG5 has the supressor grid connected internally to the cathode. The 6CB6 doesn't. Does the Sams show pin 7 & 2 connected?
Is there a tube chart on the set?
