CRT monitor without a G2 adjustment?!

[MRX37]

I found an Orion 9E9 19 inch CRT monitor today. It works, but the picture is dim. No problem I thought... Just pop the back off and adjust the G2 control on the flyback...

There is no G2 control on the flyback. Both controls on the flyback adjust the focus and nothing else. I can't find a third knob anywhere on the flyback

Could the G2 control be hiding elsewhere? If it helps, this monitor was manufactured in December 2001.
