I’m not,by principle,making Papa’s amps for money , neither public (First Watt) nor non public (or not exactly public) Pass Labs .
What I’m doing occasionally ,money involved, is :
-making my Babelfish amps for someone ,where Babelfish being a term for my iteration/anticipated version of Papa’s , born in time when Papa’s FW circuit still wasn’t published ; (when having more time/space , I’m explaining Babelfish series as unnecessary complicated iteration of Papa’s circuit 😉 )
-lending my hands and experience to someone making First Watt but ,being novice , not exactly being able/sure how to do it ; in most cases I already participated with few advices regarding needed hardware for amp in question,then I’m taking in when all hardware he collected needs some Voodoo to became whole.
However , when money is not involved , just friendship, I’m little more relaxed regarding Papa’s IP.
I have a close friend , in some circles known as SuperFi , in other circles simply known as Igor;he is DIY person too , but due to work mostly and constantly lacking in free time department . So , when I made my own Papa’s Koan M2 , he was (naturally) interested, having not just adequate speakers (Sonido 8″ FR in big horn ) but also some needed hardware.
Result is shown in next gallery ; construction was dictated by heatsinking layout ; base metal case made with help of our friend Stein (few mistakes , mostly drill size ,as usual are result of long command chain 😉 ) , top assembly made by Igor’s carpenter …. still missing Al rhomboidal net in top holes and missing decent front plate, then some feet.
I’m responsible for most part of concept , then drilling , tapping , and everything else ….
