Do the power supplies have the screw terminals on the back? If so, you
can at least have easy access to take some voltage measurements. If the
+/-18 rails are out by very much, that's probably a big part of your
problem. Does the console need both supplies to be on to run?

Ike,
I do have the schematics, but as far as I can tell, no parts layout.
It does look like the parts are identified somewhat on the schematic.
We have a 36 channel, + 4 stereo channels, with 2 power supplies.
Thanks for the input all, I'd rather not open a can of worms. Just
want the pre amps to be usable. This is a new console (to us), and I'd
say only 8 channels have pre amps that aren't super scratchy when the
pot is turned. Repeatedly turning the pots has not resolved the issue.

Do you have a manual with the power supply schematic and (more
importantly) parts layout? Also, how many channels is your console
and how many power supplies do you have?

Thanks for all of the help! I've only replaced fuses on the
power supply, how do you go about trimming the 18v rail? I'm
going to look at my schematics in the morning to see about the
DC action.

In addition to cleaning, you may also need to
null out the dc
across the pot. This dc varies as the gain pot
is rotated
causing noise. On the Series 1 there is a
trimpot for this, I
assume the Elite is similar, but I don't have a
schematic.

We have a Neotek Elite we recently
installed, and every mic
pre pot is super scratchy. I did some quick
research, and
bought two products; Deoxit Fader F5, and
Deoxit Gold G5.
Should I use both, or one of these
products? Any tips on this
procedure? I figure I need to pull each
module and spray it in
from the underneath. Going to wait for
someones 2 cents before
proceeding. Thanks in advance!!
