I was cleaning up an old RF Punch 60x2 trans-ana amp that I got from someone several months ago and inside I noticed two little dials inside on the main board. They look just like the left and right gain controls on the back\outside of the amp.
Here is a picture. I circled the dials.

Does anyone know what these do? They are easy to adjust with a small screw driver or knife, but I don't want to mess with them without knowing what they're for.
Thanks
