Very nice , big 35A bridges (I like the power supply custom boards).
Proper 90 degree IPS/OPS config - that will fit the smaller case.
Good job !

I should thank you for making this awesome projects mister OS I'm not as advance as you guys are but I do like to learn, I have been reading this section for a while but I guess it went way too advance for me I only good at layout placement making them look good the best I can, I also understand that what you do is not easy at all and it takes many hours of moving cloning paste analyzing and more 🙂
I did the Slewmonster 5P from you and mister JK awesome layout I already safe it for later 🙂 "choosing the IPS is hard 😕
but man so many IPS PCB's that is like you are in bakery and they are too many sweet things to chose from lol ,😛 now we have KYPTON-V wow ! 🙂 very cool

"Eyesee" will be born -
It's not that hard , Vargas. You have to start somewhere. 😕
(often in utter confusion) 😱
Like the "Eyesee" (below -schema)... just a TL072 or even a NE5534 (oops)
It starts with the Concept (eyesee V1.0 .asc - below)
What a simple amp - .001 to .003% 1K/20K , better than the old DX (before
the "blame").
Had to read the LT1007 paper .... http://cds.linear.com/docs/en/datasheet/100737fbs.pdf
Had to read " unity gain buffer" section , now "it eats square-waves" 😀.
What you don't know can (frustrate) you.
It needs more gain (op-amp is only a buffer with current feedback).
HEY !!! , it's a bloody CFA - 😎😱 Confusion fading .... 😀
Edit - it clips nice ! (below 2) Big waveform for a little cheeeep.

Etch that Kypton- C , Thimios's scope test of it was the best CFA in -
1. clipping - perfect !
2. offset 1mv - perfect !
3. squarewave 20k, 100k , even 300k - nearly perfect.
Not a 3 transistor wonder , (12) but all run cool (and perfect).
Try the CFA - the "corporation" never got to it. 😛

I etched the Krypton-V this morning. Burning resistors so set it aside for tonight. Further investigation in the morning.
When I slow down enough I'll run some sine and squares through my Krypton-C and compare them to Thimiios's results. I'll compare them to the original CFA-XH and the BV 1 and 2 mods too.
Sorry, a lot of irons in the fire right now so not a lot of time for comparisons. I did listen to the Badger all day while I worked. Man, that is one nice amp! Next week sometime I should have both Kryptons and Valery's new hybrid ready for testing. I may get to the Kryptons this week depending on how my trouble shooting pans out tomorrow. I need to mark up a schematic with voltages of the spice file. I'll try to do that first thing.

What about the protection in my signature ?
It looks a little complicated because a lot of added features but in fact quite simple. It works with a unique double OPA in my personal amp, is universal and can work from out the amp as well. And all analog 🙂
And it is an interesting tool to figure-out what's happens in a perfect amp playing music on real speakers: Not as perfect as expected !

I don't know whether you've considered using the Arduino's built-in watchdog function to reduce the likelihood of lockups? It's not infallible, but would offer some additional protection.
Hi Currentfolw - no, I didn't utilize the built-in watchdog (as yet), however - I use ATMega-based controllers a lot - never had a single failure (unless there is an error in the firmware, but this one is simple enough for keeping it error-free 😉).
Cheers,
Valery
Roger that OS 🙂 so KYPTON-C will be then thanks,
man square wave from 20k,100k even more that is crazy wow 😀
I will then concentrate on KYPTON-C
oh by the way thanks Thimios and Terry you guy are awesome testing the IPS
awesome 🙂

Hi Valery,
I also use these devices for a variety of projects - ATMega168 to ATMega1284 mostly and I find them extremely reliable. They're superb devices and even better when used standalone without the Arduino IDE limitations, using the AVR Eclipse plugin (in C/C++) and an ICSP programmer. One is used as a fully programmable, 4-zone thermostat + boiler weather-compensator + datalogger and regulates my home heating using TPI (Time, Proportional, Integral) control 😉
Ahhha )) I see a familiar protection board in the new layout 😉 You've got a very cool transformer on the board - looks very similar to the one I use.
And - of course - the SlewMonsters!
Man-size transformer 🙂
Coming out nicely
P.S. I'm also preparing for drilling the heatsinks...
It's a tough go fitting everything in a rack mount chassis. I still need to figure out a set of mount perches to test tube inputs. The tube supply will need to be in a bulge in the rear cover.
Drilling heat sinks is slick here. I do it on a milling machine with a readout. Everything bolts down perfectly the first time unless a tap breaks.😡
