[sdiy] MXR Pitch Transposer

[grant at musictechnologiesgroup.com]

I might have one somewhere ... but it won't be easy to find. And it
might be a 6070, not a 6072 (not sure what the difference is).  I think
DAC-76 or DAC-78 could be another possible cross.  We need to find the
data sheets first and even that might be a fun adventure.  The various
versions have difference transfer curves (u-law vs a-law). Do you have a
schematic?
