Wire for repairing HV problems

[maxhifi]

In my "new" Silvertone, the wire between the 6BK4 plate, and HV rectifier filament has lost its ability to insulate, and is arcing. Shows up as random snow in the picture... had to have the chassis out, and lights off to see it.

Has anyone here bought this stuff off eBay?

Looks like it would work, and give me lots of extra for future.
