OK, done some more testing with this today, and it seems that
everything else works, and actually the buzzing power supply doesnt
seem to be a problem - seems pretty much the same with or without the
M15 plugged in. My problem is that the M15 outputs a buzz (seems to be
the same frequency as the power supply buzz) which starts with
distortion then decays to a more sine-like buzz. Its def not the
oscillator tho, as tuning makes no difference, and seems to be pretty
much every jack socket that makes that noise. 

The guy I bought it from has said its cool to send it back and get a
refund, but would be good to find out if its actually got broken in
transit or if there is some kind of compatibility issue with the A.Sol
case/power supply.
