Went to recap this WG 15V2000, and the tube where the HV lead goes in is covered in a thick, tar-like substance:

I assume this is Not Good. What the hell is it and how soon will it give me cancer?

It's normal. Don't worry about it. It's the plasticizer leeching out of the rubber/plastic used to make the anode lead, and the material breaking down a bit. It's most definitely not leaking out of the tube. You can dissolve it with brake parts cleaner, and make the anode lead not so gooey, but be careful trying to clean the back of the tube, you don't want to take off the black/gray graphite coating underneath.

Okay, great. Pain getting this HV lead out, the rubber is very hard. Deflection board is capped, on to the HV & diodes and I should have a nice monitor.

Yeah, occasionally the HV lead gets so hard that it turns brittle and the suction cup will break apart. If this happens, you can usually replace it with the anode cup/lead from a junked monitor/TV. I forget this exact monitor, but on most color monitors, the anode lead is permanently attached to the flyback, with no good method of replacement, but on black and white monitors, it solders onto the HV diode clip. So, I usually just replace the cracked/hard/brittle HV lead with one clipped from a junk color monitor flyback, or junked TV set.

I have nothing handy, so I reused what I had. Fired it up and it works and looks great… when it works. Going to drop a new big blue in tomorrow night and recap the AR1, then see where that leaves me.
