Setting the gain of Jeff Rowland Model One

I want to set the gain of my Jeff Rowland Model One amplifier.
I have removed the driver module from the main board. As described in the user manual, the back of that module shows some sockets meant for jumpers (see attached picture).
Unfortunately I don't know how to place those jumpers to set the gain at 20, 26, 29.5 or 32 dB (the values indicated in the user manual).
Can anybody help me?
Thank you!

There is little guarantee that posting this same message over and over will solicit a different response. However, if anyone would know the answer to your question, the manufacturer or a dealer would be a sure bet.

Good luck with your repetitive merry-go-round!

Someone may visit a section of this forum and not another.
My question concerned a device that is a vintage amplifier.
Thus I posted to the amplifier section and to the amplifier one.
What's the bad?

Thank you for your suggestion.
