Note that measuring the high voltage on a tube requires a special
HV meter. You're trying to test something in the area of 8-9KV here,
at very low current levels. Do NOT try to measure it with your average
VOM; it's not designed for it. FYI, a color tubes' HV is generally
20KV or higher. Don't poke around with it unless you have the proper
tools and someone standing by to shut off power in emergencies.
