Look at CRT socket. The 3 color outputs have white paint on
the PCB. They are marked E B & C measure the C in DC volts. The G-2 should be marked too. Use a meter rated at 800-1000 volts as it can be adjusted that high. Normal voltage is apx 400-500. Almost all in line tubes will have the same set up & its common to make tests here. 73 Zeno LFOD ! |

The three color controls had no markings for what was what, and the only things with the E C & B markings are transistors on the neck board. I tested the voltages on the controls and got nothing on DC, then figured I misread something and tried AC. Still no voltage. I grabbed another meter and still got nothing. So the issue is the neck board? Have to admit it, but the high voltages can be a bit scary sometimes. |

Measure at the C of one of the transistors. Not the
controls. |
