Most Greedy Greedy Greedy Boy (of them all)
Yup , that one would be Me , Mighty Moi , ZM
What’s the Catch ?
Nothing …. except here’s the story ……
Culprit : I was constantly bugging Papa about mostly everything , squeezing both question and answer of 42 ….
Consequence : so he in one moment (certainly desperate move ) came to idea that bribe is the way to cope with me ……..
(Fact: Papa is naive ; Do not tell him that simple e-mail addy block is more than sufficient to solve all his ZM related troubles…….. though if he really start using that , we’ll have mass suicide of DiyA Papaland members ……. sometimes I have an impression that e-mail traffic to Pa is almost big as regular posting on forum )
So – he asked me what do I want , from pretty extensive list of things , he’s working on lately;
As usual , I said – nuttin’ , frankly not needing anything , being 2 (3, 4, 5) years late in things obligated (from various reasons) to build for my self …..
But – after repeated reading of his proposition , greediness started getting better of me , and I asked him for few more words about DEFiSIT ; when he replied , I instantly had impression of (my absolutely fave) M2 , with heavy twist(s)
so ……..
now – few pics from recent BAF....... Papalecture , DEFiSIT simple , DEFiSIT no values , Real MCKay one and two , little more detailed schm.

Aha ....
Lucky me ..... crystallization moment of entire ( taking advantage of naive gift giver) operation , was when I realized that I had opportunity of my personal Pony Express executive being in USA and soon going home …… with possibility to fill some space in luggage ;
So , I got finger (not that one !) , pulled entire arm ,and result is - nice FW box , arriving at Pony Express rider temporary address :

as agreed ....... what was really agreed is DEFiSIT kit , in most beaten FW case , as we know that Papa is using them for all sort of prototyping .....
well , he tricked me - case isn't beaten at all .....![Mad :mad: :mad:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

as I said - Kiddoe is handy with Allen key ;
per my instructions - everything is dissmantled in pieces , for better usage of suitcase space and for lesser amount of Customs curiosity , at arrival home ;
approach resulted fruitfully - Roentgen in Customs is still cleverer than operators![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
few days ago I started assembly/disassembly/assembly ;
Reminder : Assembly of Japanese bicycle require great peace of mind.
PSU pcb is obviously (same as in BAF specimen) from (early?) testing/production of SIT-1 ; and - Pa obviously used that pcb for some tests , and few power resistors in CRCRC are not same in channels (yup , dual mono PSU) ...... lucky me (again) , if not brain , I have great piece of mind , so I spotted that ...... also one cap per channel used in other purposes , now connected to other ones

I'm not Fearless Amplifier Builder , as Papa certainly is ..... and I'm anyway used to make unnecessary changes to his circuits , so some trace cuttin' and one additional resistor , change of trimpot value , multiturn just because I'm Chicken ![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

just from habit - my fave Philips 1uF MKC , as bypass on C1 and C2 position
did I wrote that Papa sent all caps in bubblie ?
....... more precisely - all parts , except small metal films![hypno1 :hypno1: :hypno1:](https://files.diyaudio.com/forums/images/smilies/hypno1.gif)
I also changed C2 to (also) my fave (125C , so industrial?) ELNA 470uF/35V

Ok , Donut time ;
He sent me schmtc , but he didn't wrote about rails value ; after several emails (yup, me bugging again) , I finally got that name of the game is PapaSit's sweet spot ...... so set voltage and SIT will sit in proper current
![rolllaugh :rofl: :rofl:](https://files.diyaudio.com/forums/images/smilies/rolllaugh.gif)
Donuts- I have them zillion years , never had some use for them , until now
potted , shielded ; had to drill bottom Donut all through (careful with that Axe, Eugene .... it's easy to make a short , so drill bigger hole in shield pan on top)
50Vct , so CT going to GND on PSU pcb , while start and end of secondary are connected to just two diodes of Graetz bridge , routing neg to neg PSU input

Is that your own magnetically shielded transformer or was that supplied?
I'm curious to know a little more about it.
