The 1X2 is rated at 15KV PIV. So, it would break down. They're probably running the 16GP4 at 10KV or less, maybe 9.5KV. That would still cause the 1X2 to break down.

The 1X2-A, and 1X2-B are rated at 20KV PIV, the 1X2-C is rated at 22KV PIV.

If you can find a 1X2-A,B, or C then it would probably work without the modifications you made.

I have a 1X2B. According to my HV probe the 16GP4 is running at 14-15kv right now without the immediate sparking failure on the 1X2 which would be at 28-30kv PIV? It sounds like the 1X2 isn't going to last that long if I'm running it that far over spec. The CRT might not be happy running that far over spec either! One other thing that I have been pondering is what kind of X-ray emissions the 1X2 might be putting out with the voltage that high.
