Testing has shown that two 9v batteries in series do not provide adequate current.

So I powered with my HP bench supply that puts out 300ma and it sounded fine. When pots at minimum I can detect little to no effect on the sound and gradually rotating pots provides a subtle but increasingly noticeable effect.

I will finalize the mounting of the board in the chassis and then test with the hissy Scott 112B, but I am hopeful for $20 this might be a good solution. With adequate power supply the effect was subtle and not objectionable at all until more than 1/2 way to max on the pots.

Hell maybe I can buy some additional cases and make a living selling DNR units! (but not taking orders yet please)
