How common is this?

Hello,

A friend gave me 4 chassis to be used with 14-15 inch tubes, however, when I checked the neck connector, I found this:

I think this is the first time I see a "double G01" connector. My tubes only have 1 pin there. I don't know if the chasis can be modified to use only one pin.

It's for a dual focus tube.

PC computer monitors used these, but I would be surprised if there was one that was under 15". More like 17" and over.

What does the chassis look like?

Like this... In the good theory, these are tri sync. Now I wonder if a computer CRT tube would support a 15lhz signal....

I think I sould try with a trinitron... AFAIK, most of the Trinitron tubes have double focus.
