After the Monday-of-doom, I replaced my fuse, plugged in my modules.
They seem to work... with one exception.


When I plugged in the A-190, my two oscillators produced nothing but
weird, very low-level ring-mod-y noise. 

I tried plugging in the A-190, *without* the AD5 - same problem. 
I tried plugging in the AD5 alone - no problem.


1) Has anyone had an A-190 cause this?
2) Could it be a problem with the AD5 instead?
3) Could it be some weird short on the +5v part of the rail instead?

I've no idea what to replace, or whether to look elsewhere in the box
for some other cause.

Any help - as ever - much appreciated.

P.S. I also found I started getting slight shocks from the case after
use... :-( makes me very nervous.
