NPNG - need repair help

Hi all,

I have an NPNG DMP-2NW that needs a (hopefully minor) repair.

The problem is no signal on channel 1. No action on the meters or anything.

I do get a quick spike on the meters when I toggle the Hipass switch, not no audio.

If anyone has schematics, or contact info for someone who does, it would be appreciated.

Looking for the schematic myself. I think Karl is going through some stuff I read. Feel bad for him and I am not in any way offended. We don't know the situation. I have a stuck meter and he said back when that he would send me the schematic but I didn't hear from him after that. Hope things are okay his way.

Sadly NPNG´s Karl Diehl passed away last year.


I'm about to buy a used NPNG 4NW. The most wonderful preamp on earth. To be able to repair the unit in the future, the schematics would be very helpful.

If someone have it. Please PM me!
