MOTM

I'm having problems with my 190 VCA clicking.  Each section of the dual 
VCA has been tested and they're both clicking.  I've taken the 190 out 
from the cabinet and adjusted the two trimmers while running a sequence 
of snappy EGs (zero attack / moderate decay) into the CV inputs.  It 
seems that the two end points of the trimpots make the CV bleedthrough 
relatively loud, while putting it in the middle reduces the clickiness, 
but it is still there and quite noticeable.  I've tried both a MOTM-800 
EG and also a Synthesizers.com EG with the same results.  Is anyone 
else's VCA clicking?
