Looking for schematic and board layout for Radio Shack Model 21-543 DSP 40 Noise Reduction System

I'm wanting to change the switches that select bandwidth and filtering type
to pots, if this is possible. Any help is appreciated. Thanks in advance.

I had one of those units. I don't think that using pots will be
possible. Its a DSP, the switches change the filter algorithm.
