Well, I got the blanker all sorted and did a quick and dirty convergence and setup. It's quite watchable, though not perfect, yet.
One thing, while I was replacing the HV lead (the old one was, well, leaky), I cracked one of the posts in the cup that holds the HV rectifier socket. Apparently, it's the most brittle plastic on earth

So I have to hunt a spare down. I'm guessing it is the same as a CTC-15's, the HV box on this set looks identical to the '15.
