Hi Mike
That sounds a bit 'defeatist' in that you can get supplies relatively
easily, or get your supply repaired.
Where are you in Germany? There are various 'Techs' around just a case
of finding one.
Describe the 'noise' and there is a good chance someone here can
suggest which chips or whatever could be changed.

Hi! I'm Mike from Germany. I own a 1986 / 87, 34 channel Neotek Elite
mixing desk. Unfortunately the power supply unit is broken and the
stereo sum generates some noise. Since I can't find a suitable
technician to fix it I'd like to sell it now. Except for the defects
mentioned above all channels work perfectly. Is anyone interested in
the complete desk or maybe even just parts of it? Or does any of you
know someone dealing in such desks? I've attached a few photos.

Hi Matt,
The supplies troubles are probably through. In fact it is not the
original unit anymore, it had been nearly completely destroyed once, a
tech then rebuilt the +/- 18 V voltage, also the -25 V voltage. Those
voltages can be adjusted via a spindle potentiometer. Another tech then
gave me the hint to just move those potentiometers a little and then
readjust the voltage. It worked out fine, noises are gone, at least for
the time being. I just have to take care of the Mute Logic circuit, that
one's going a bit crazy right now. The desk is located in the Ruhr
Metropolis, in between Dortmund and Düsseldorf.
Regards
Michael Jesch
