The brightness and contrast controls work. What's interesting is the black bars spread a little as I adjust contrast. The horizontal hold doesn't do very much. I haven't been deep in the set but I'm wondering if it's a coil. I turned it about 4 complete circles before anything happened. Also there is a little ringing from the yoke.
Also I checked the 255 volts source and tube heater voltages on other tubes but I did not check there. I will check and report back.
