Wiring the ITT HQ sound board

[Hamltnblue]

I Just received a call from George of Itt who went through it with me. Turns out I have a version that does not stop when you remove the low voltage. His current version does. He's sending me a replacement unit no charge.
Excellent service

Thanks I'll try it tomorrow.

 Pin 9, BELL Positive trigger, is the only connection required between the two boards.  Connect this terminal to the ITT board's "trigger" input.  The ITT module gets its own separate power input.
