In fact the grounds are NOT all tied together. I just attached the first wire (BLK) that ohm'd out to the first ground pin I touched. I will correct tonight and report back later.

I fixed the circuit and double checked all the connections. I still can't get it to work. I am frustrated.

The only thing I still dont understand is how a VGA "Y" splitter can work for the signal. 

 
                             |----------->Monitor
VGA ------>Splitter-|                                                 ???
                             |------>Circuit ------>Gun

If the circuit isn't in line with the monitor how is the signal at the monitor capable of working with the 15khz gun? 


Or does the circuit make the gun work at the VGA 30khz signal?  What am I missing here?

I don't understand what you have wrong with the scheme :

                                  31Khz
      31Khz                |----------->Monitor
VGA -------->Splitter-|    31Khz              15Khz                             
                                |------------>Circuit --------->Gun

I guess what my question is - what exactly is the circuit doing? 

I was under the impression it took the 31 Khz signal from the PC's VGA card and converted it to 15 khz so that the 15khz gun could work with the signal on the screen.

Or is the circuit taking a VGA signal and modifiying it to something the gun will recognize and has nothing to do with the actual 31 khz signal at the screen?
