sounds good... BTW to where did you move the in and out cabling for
this disc ch?
did you just move it, e.g., down one ch of the disc? or did you move
it, e.g., down one ch of the disc and also move the chs below
this one down one too?

i.e. neighboring PS706 chs have a small amount of timing cross-talk -
we want an open ch in between...

not a big deal - i just wanted to chekc...... thanks
