Hi Scott,

All the reported voltages were measured with the supply disconnected 
from the rest of the synth.  I did measure some voltages early on with 
the rest of the synth connected, but I didn't mention those readings in 
my previous email (I thought my first email was already getting long 
enough as it was!)  I *think* when the supply was cabled in to the rest 
of the synth the -15V line was <1V and the +15V line was sitting about 
9V or so, but I may be remembering wrongly.  I will reconnect it 
tonight, re-measure and report what I find.

Thanks,
A.
