Emax

Hello there
This is a strange one ; After not using my Emax II for several months 
(I have an E Synth which translates 99% correctly but does have 
problems with certain filter/Q settings. Anyone had the same ?) I 
booted her up and found the output dead, along with the volume and 
data sliders. First checked the sliders to find they were still OK 
and then read here, to clean all the internal connections etc. Voila !
the outputs came back to life but the volume and data still didn't 
respond except in the recalibrate mode. I get a 1003 reading in the 
Pre Minimum position and 0394 in the Pre Maximum ! Obviously they 
should read 0. Any ideas anyone ? thanks, Lyn.
