Bear in mind projection's use voltages up to 25,000 volts, which are not fun to get tangled up with, though the horizontal output pulses (lower volts but more amps) arte probbably more dangerous. If you're unsure at all, don't mess around in there or power it up. Of course, if it's sat unplugged for a long time, it's safe, but be aware the CRT is a fragile little thing.
I'd expect at minimum, the HV box will need to be kept religiously clean...
Don't these sets use that Norelco setup?
