Emu XL-7 & MP-7 User's Group

Thank you very much!

Indeed it could be related, if there is some electrical "current-
leak" on that PCB, it sends out an OFF-signal if I turn the volume 
knob! There is some logic in that, at least to me (no expert here) 
I'll give it a try!

user have problem with a "buzz" noise in the headphone. Maybe your 
problem have the same "source". It apppear that the jack headphone 
isn't corectly electricaly isolated from the box. So you will have 
to open your box and to throw off the jack headphone and the light 
(  the contact of the vomume knob too ). After the but is to isolate 
these components from the box ( all the components ). To do that you 
can simply buy an isolant varnish and to cover the pieces which are 
in contact with the box ( the part of the box too ). After doing 
this operation it seams that the problem of the "buzz" has been 
deseappear. Maybe it will work for your volume knob's problem.
