... Any help would be appreciated. I'm rusty on PDF creation.

Hi Pete!
I've sent you a PM

OK, gleaning as best I can. There are three possible input boards: SPOOKY, WOLVERINE, and KRYPTON C and one output board OSC????? Are any of the input boards n jfet cascode? Where are the most "up to date" 3 input board schematics PLEASE? I found the wolverine, would like to see Spooky and Krypton C. Thanks, Ray
There are more. There are the Symasui, CFA-XH, Krypton V;; and Valery has the Low TIM hybrid and most recently the Clean CF-FET.
Great Caesar's ghost! Choices, choices Thanks still4given! Let's hope for a web page with everything on it. Comparison pics of harmonic poles in each amp. Ray
I made a raw preview of the the Construction manual using bookmarks, external and internal links. Need help to build the structure of document. All texts and photos are fake for now. Thanks

That is great.
Can someone let me know where I can find the latest layout and silk screen.🙂
Thank you very much
I would like to build these IPS.

If you're hand etching, post 4729. http://www.diyaudio.com/forums/solid-state/248105-slewmaster-cfa-vs-vfa-rumble-473.html#post4101624 If you're getting boards manufactured I can email you gerbers.
I just thought of a word:
Autocascode
We should surely be using it. But what does it refer to?

Very , Very pro style to the format.
Now it will be up to me to make the content (in english 😀).
I can comment for image/schematic placement in my text and identify what
graphic I want there. It would be up to you to "vectorize" (I use standard .JPG
for just about everything_.
Very good , wish I knew PDF to that point (I'm "spread too thin" - now).
"Bonsai" level PDF's (better even) !!
The first 4 guides will be spooky , wolverine , K C , and symasui (the ones I
have built).
BTW , in my signature -"Fidelityforce .com" has ALL the slewmaster files.
NO more looking around!!

There is a "autocascode" buck convertor"
Show what you speak of ??

Hi OS,
I have been wondering how you feel about the Symasui? You talk a lot about the Spooky and Wolverine but very little mention of the Symasui. Is that because the Symasui isn't built into a case or is there a reason you prefer the other two?
Thanks, Terry

There is nothing majorly wrong with the symasui. I stuffed it , ran it. It does take
longer for it's servo to settle (had to set my control board to over 5 sec.delay to avoid the DC alarm).
A few value changes to the servo /VAS will fix this.
Once they have a home ( 2P OPS's) , I will finalize these tweaks.
It sounds like the spooky SQ wise. Real good bass.
I'll update any improvements in the build guide (no circuit or PCB changes)
My wolverine choice was the fact it was not cascoded , max rail capability
for my "hungry sub". Most "rock solid" lab amp.
Kypton C just has a few screen errors (jeff's PCB) . I saw why 😱😱 ...
one of my earlier schema's had that wrong 10k servo resistor (not Jeff's fault).
The "spook" is my preferred choice - personally . It has the bass and the speed
to produce quite the detailed soundstage. John Curl and Pass chose this
topology wisely (HK , too)
So , those 4 will get some real attention (manuals). I'll put enough history and
circuit operation info in the manual - you will REALLY know exactly what
makes these "tick".
Hi Guys,
I have been having fun etching boards lately and came across the Gnome layout. Did any of you build it and if so, what is the most recent schematic?
Thanks, Terry

Wow! 660 pages later, I will get to finally build something and listen to it.... been waiting for things to settle down and final decisions made. If those who have devoted their lives to audio circuits prefer the topology of the Spook, that's good enough for me. Next will be pcb and then a kit by someone, I hope?

Richard,
There have been boards all along to build the different versions here. The parts ordering has been on the individual though as everyone seems to use different devices depending on availability in their countries. I think you know how to use Digi-key or Mouser by now.
It's going to be the Krypton-C for me a very nicely designed CFA type of amplifier with servo control. Take you pick, nobody has complained about the sound of any of the designs that Ostripper has designed. Everyone seems to be happy with their choices in the end.

1 month of "spooky" ...
Quite satisfied. (spooky V1.2 ,btw)
- it works - electrically stable to the microvolt. 🙂
- ran the kypton C , the spook requires -3db less bass on the DSP ??
- When you get a "rollin' with the music (real loud) , spook bass becomes
"legendary" . NO OEM even comes close (I have 2 oem's).
- Directly had the HK990 with a cascoded "spook" front end in for repair.
The "brother amp" sounds nearly the same (a 2500$ receiver).
So , build the spook + slew OPS .... get a 2.5K higher end audio amp.
Build it with bigger , badder power supplies - get a Pass/Parasound.
I see no way this can not be (I even put parts in wrong on the spook , It
worked despite this ??)

can someone post final schematic and pcb layout of spooky ips?
spooky 1.2 is in my signature site address -
