Who's the designer of the Threshold SL10?
Eric Lauchli? Nelson Pass (the obvious of course) John Curl is named sometimes as a co-designer.

My first Threshold product I bought in 1990 was a FET One the successor of the SL-10 that's why I asked about Eric Lauchli because I do remember on the PCB of the FET One the credits read: Pass-Lauchli preamp.
@NP
Eric Lauchli did work/was hired for the Threshold Corporation when it was situated in Auburn Cal. when I'm correct?
Why did you decide to (partially) outsource the designwork for the pre-amplifiers at Threshold and PassLabs if I may ask?

It was not outsourced, it was in-house, just as it is now.
I don't personally have a need to do everything. There are features, topologies and
parts we favor, and prototype product is evaluated by several people before it
goes anywhere.

I'm aware as a you are probably, that intellectual property falls back to the employer when the work in this field has been done as a employee.
So in house is indeed not outsourced.
Or you could have your sister file a patent of course 😉
But my question was if Eric Lauchli who was credited as far as I know on the PCB alongside you of my and for that matter all the other Threshold FET Ones, did actually some of the design work for it or not.
You initially stated that you designed the first two preamps of Threshold and stated that after that Wayne (Colburn I assume) and Mike Bladelius did the preamps. You later corrected that but that lead to my question why power amplifiers is more your speciality as all your patents reflect.
