   Thanks for the input. I had a friend of mine build me a voltage doubler and after it was installed
 I used the 1629 eye tube and it works very well.

Hi Dan, Wayne here in Phoenix.  It's been a while since I rewired a 6X6 for a 6G5(6U5) but if I recall correctly, you just interchange the pin 4 and pin 6 wires.  I was up in Calgary for a couple of months this summer but your whole street was blocked off for construction so it kind of deterred me from dropping by.
