Company of "The one and only", Nelson Pass.
Here you find information eventually including schematics, pcbs or links to forum's discussions about various designs by Pass Labs.
If you get hold of one of the service manuals, always remember
- "The service manuals are not DIY projects. You
- will get an extra merit badge for navigating the
- treacherous waters of any service schematic drawn
- by Pass."
Don't trust mentioned voltage drops, bias values. Calculate them yourself to check!
