Help Wanted: I Need A Remote Control for EDGE G2 PreAmp

I have an Edge G2 Preamp, but no Remote Control.
I have an Edge G8 - Edge G2 system.

I would like to purchase a Remote Control or help to fabricate/create/program a remote to operate the Edge G2 preamp. Or, any other method to remotely control the Edge G2 preamp, i.e. coding with a universal remote, etc.

Edge is no longer an actively functioning company and sourcing a remote from them would be extremely difficult. Same with Maker.

I also need the operating manual for the Edge G2 preamp.

Anyone with information on how to make this possible would be greatly appreciated.

Thank you.
