Correct. I was speaking more to the electrical compatability between the 2, and they seem to be a perfect match. Bob noted that the gun was almost identical to a production 15GP22 one, only a few added supports differ between them.

Wouldn't it be nice if you could lay hands on the engineering notes for your prototype? Delay line questions, burst frequency, convergence supply specifications, how and if high voltage is regulated, what tubes go where, the list seems endless.
It looks as if this thread could last a while. That's perfectly fine by me.
