PCB Line dancing made easy

There are a couple of occasions where the arcade PCB outputs at a different scan timing to the CRT where as an arcade monitor can accommodate this by geometry compensation..consumer CRT, not so much. 

You will have 2 options:

1. Open up/Go to the service menu of the CRT and adjust the geometry for that couple of games that requires the adjustment.

2. Alter the signal before it reaches the CRT.

I chose to do the later:

I bought 3 H-Shift circuits with built in Sync leveling capabilities to ensure compatibility with non-arcade monitors.

So it interfaces between the arcade PCB and the Super Gun. This circuit is not required for arcade monitors so it is solely for consumer (or professional) grade CRT.

Please excuse the bad reflection, as you can see, the image is cut off at the bottom and you loose quite a bit of detail of the HUD. This is the image you get if you use the PCB directly to the Super Gun or if you have the interface turned off.

This is the image you get with the circuit turned on, notice you can center the image where ever you like without affecting the other geometry setting. All this is accessible at the circuit so no need to change TV settings at all.
