Jeff Rowland Model 112 Power Amp Question


Does anybody know how to change to gain on this amp. The owner's manual doesn't say how and I have contacted JRDG, but they haven't responded as of yet.

I want to lower the gain from 30dB to 26dB.

Thank You.

Sandstone, a few years back I changed it to the higher gain. I called Rowland and they gave me instructions. It was very easy, but now I can't find the instructions. It was just switching some jumpers. I don't want to open up the amp and then try to figure it out. Just hoping someone knew the specifics. Thanks.
I would call them/him instead of e-mailing.
If he does not call back - then call again.
