Mad Mouse Troubleshooting

[jay kolaric]

I am having trouble getting tomg's mad mouse synth working.
I know a lot of people have put this together and I was wondering if
there was a checklist of tests to isolate problems.
Such as outputs to check for on pins A-Z, AA-DD, and LED1+2.
I haven't had much time to test but what I have found is as follows.
The led lights up.  It is always on no matter what position the on
switch is in.  I don't think this is supposed to happen.
I have checked for +12 and -12 in the smoke test section and this seems
ok.  (11.94V and -12.16V)
With or without a cv input the mad mouse always makes a low frequency
low volume noisy growling sound.  The controls have minimal effects on
this sound but the minimal effect appears close to what it should be.
eg the volume pot makes it louder, resonance changes the sound a bit
right near the max position.  cutoff frequency appears to change the
sound a little etc.
I also have a midi2cv8 in the same box.  Both boards run off a single
12VAC 500mA transformer (is this ok?)
The midi2cv8 output test works.  MIDI data causes the MIDI Activity LED
to blink.  I haven't done the MIDI In test yet but I think this will
work.
Thankyou in advance for any help.
