[Vectrex - screen compresses slightly when moving joystick]

Hi,

I just received my Vectrex which is a NoBuzz Version.
All fine, except one thing...
I have tried to capture the effect in a short video (link below), but I am not sure if this comes across well?

The problem is if any of my controller is plugged into 1st player and I move the Joystick, the screen becomes horizontally compressed.
This becomes very visible when text is displayed.

 

Checksum = 7ADB

 

If anyone has any idea of possible root causes, that would be really fantastic.

Many thanks for your help in advance.

Best regards,

Sven.
