Got a few noise/psu issues of my own and I'm still looking for a good
L.A. based tech. Anyone know anyone good? I had someone great, but
he's too busy for my little jobs now.
Cheers,
Kai

Thanx for all the answers!!i did have numerous problems with my
elite mainly cause i never had an experienced neotek look at it.to
be honest i was waiting to start recapping it so i wanted to fix the
main problem first. For years i had the spike problem which never
actually got fixed even after rebuilding the power supply!i decided
to get a brand new one. Up to that point i had installed proper
grounding to the console so i had no hums. Having said that i get
tons of crackle from pots an other minor faults but the console was
operational. Because of the problems of my old supply i had the 4
stereo channels on the right of the master section disconnected and
those channels did show similar problems with mutes. I cant b sure
it was the samw thing tho as i had to compelely disconnect them from
the mainboard. So after swapping the ps all the spikes went away. I
had to cut the cable from the old supply to use the same connector
and mike stoika said the color code is right so its all connected
properly unless some of the groung pins should be somewhere else!!.
Anyway my main problem at the moment is hum when i have bus switch
pressed.i suppose its there but if all channels are muted its barely
there.if i unmute a channel i hear the hum a little and if i press
the bus switch its really loud to the point its actually unusable.
At the same time the moment im muting or unmuting i get these clicks
i mentioned before. I have dozens of other noises from defective
channels and things but tgis hum is everywhere independent of
channels. I get it at the cue outputs in the studio as well. I hope
this more detailed info helps. I wish i could get a good tech to
have a look at it so i know at least what needs to be done!!!thanx
again!!

Hi Nik,
Two things:
1) If you are having any weird behavior with mutes on an Elite, the
1st thing to do is go through each module and tighten the nut and
bolt that goes between the upper and lower circuit boards (just
between Aux-4 and the top Eq/Filter/Insert switches). This
connection is critical for the correct operation of the Mute FET's
as it carries the ground connection for that circuit.
2) There is something fundamentally wrong with your console. We
have been kicking this around here for something like two years
(actually since Feb. 21, 2008 to be exact). One thing I would check
right away is to make sure that ALL of the ground connections that
come in from the power supply connector are securely tied to the
frame of the console. This usually happens right below the L & R VU
meters. Make sure that all of the connections are there, and make
sure that they are tight. I think you have a mid 80's vintage
Elite, which also had a ground strap that ran from that point to
the motherboard in the master section. Make sure that is securely
fastened to the motherboard. I would then check to see that the
frame is securely bolted together.
Let us know what you find out. One more thing: Please give us any
and all pertinent background information...like especially if it
WAS working and then this cropped up, AND, if you were inside the
console for any reason before this came up.
Best,
Ike

Hi Nik,
No, it should be quiet. What kind of noise are you getting with
the mute/un-mute cycle?

Ike

Hi everyone!
like a recent discussion here i have really bad noise problems
on the bus! I recently changed the powersupply of my elite and
got a new one from neotek which solved a few problems i had for
ages. Now i get really bad hum when i switch to bus on the
channels. Also all channels make noise when muted and unmuted.
Does that sound like something common?
Thanx
