I have a problem with ground hum from my recto!?

I'm using the external switching jacks to control channel 2 and 3 with my GCAS.
It doesn't apply when I'm on the clean channel!

it doesn't do any hum when I using the Rectifier foot switch either.
Only when i using the external switching jacks to my GCAS.

I have seen a couple of topics: one is that you could isolate your rack with humfrees so i tried but its the same.
someone said that you need to use the Y-Kabel!? haven't tried it yet thou.

(this topic is on the Voodoo Lab as well)

any thought!?

Kind regards!
Chris!
