Papa’s Koan (M)2 , an amp for living room | Zen Mod Blog ..... :
As you maybe know , maybe not – I’m begging Papa all these years for adoption ….
I’m not exactly desperate to live in US of A , but idea of lifelong exploration of his Ark is sooooo tempting …… 😉
However , maybe my nagging is main reason why he is throwing me da bone here and there , to keep me busy . occupied , puzzled ……. and feeling not worthy ….. 😉 One of previous occasions of thrown bone is Papa’s Koan amplifier , pretty well presented at diyaudio.com in these two threads : Papa’s Koan ….. was Papa’s Surprise and Babysitter for Papa’s Koan .
Now , it’s time for new bone ………
....... I'll just repeat :
My Pa is definitely smarter than your Nelson

just few piccies , rest ( plenty) you'll find on linked Mighty ZM's Blog post ....

What is metal around the signal transformers?
screening from olde VCR tuners , what else ?
having ton of old CRT screening handy , but not enough Fe in it - it must be magnetic
just couldn't find where I put that virgin sheet I have , so I used what I saw first
Oh dear...build this or build an F5....!!! Beautiful choices...
not enough Iron in f5 , to impress Mighty ZM , in amount needed for building it as is - in form of finished amp.
I can think of myriad ways to Babelfish M2 , but only few to make it even simpler
none of them will make it better

regarding any specific info about original schematic and parts used ........ my lips are sealed
on board and off board

on board and off board

Its already well established that we cannot make them sound like Papa even with original schematics.
we can , he already passed necessary info
all you need is proper THD measuring rig
ever read Castaneda's work ?
knowledge is already here , we just need to spot it , one day

ZM, what are those black metal stripes on the heatsinks for? 🙂 btw, now I know what you mean by inp signal wire as thin as possible 🙂. Do you think there is enough room for electrons to flow, don't they stuck? 🙂 🙂
Beautiful amp! 🙂 I bet it sounds even better!

look at pics preceding ones with black strips - and you'll see holes in 'sinks
those strips are plain iron , painted , then put to close holes and increase quality of higher frequencies in sound (sort of pointing up , fooling electrons to reach higher )
