A few years back, I got a couple early-design Bose 901's for
indoor sound reinforcement use.  Alas, I did not get a Bose equalizer
for them.  Since then, they have been used with a graphic eq,
but that is definitely suboptimal due to the extreme amount
of boost/cut required to flatten the overall curve.  Does anyone
out there know the transfer function (or poles/zeros, or even a
frequency response graph) for the original 901 equalizer (or even
a recent one, fwhich should be similar)?  Barring that, is there
anyone in the North/Central NJ area who could loan me a working
one overnight for testing purposes?

Thanks.
