It shouldn't take very much, but you may not be able to fit 'em in the
box when you're done. The BBD IC is run from a clock. All you need to do
is replace the existing oscillator with a square-wave output VCO. I
think the wilson delay is tuned to 1v/oct for the BBD clock - but
really, how important is that? The Electronote Preffered Circuits
Collection has a few examples of BBD analog delays with CV-able clocks.
I've built one - works pretty well, though it's a little noisy...
