Thank you Dan, I was afraid you might say something about sync. I have only connected horiz sync as a guide I read for the amplifier install by a user said didn't bother with the vert sync and all was good. Stipid me should have made a provision for a wire on pin 9 for vert sync on the connector but didn't. Could this be a good place to start?

Now I'm figuring I need to unplug it from the crt and add a wire. Should I discharge the monitor prior to attempting the remove the molex connector? I'm worried its going to be tough to remove and I may hit the crt neck and crack it. Is there a correct way of taking off a molex plug as I always struggle to remove them from my pinball pcb's. They have a triangular catch near the pins.  Thanks
