Yes. He was back here last August and kept posting through April of this year and them nothing since. I know he is working on some new stuff. Maybe he'll be back when he has more to share.

Default last and best Spooky and Kypton-ND schematic

Hi,
I get lost in the long thread.
I'm looking for the last, well tested version of the Spooky and Kypton-ND input stages.
The Spooky here his V1.1, but OS also made a version V1.3 here. Anywere there should be a version 1.2. Which one is the best?
And for the Kypton-ND I have the similar problem .

Here is the Spooky 1.2 schematic. I have made this and found it excellent (though I've not made any of the others for comparison).

Hi Thimios,

the schematic you posted is very similar to that linked in the first post of this thread (only two transitor types are different and 2 resistors).
But one thing seems to me is wrong.
The feedback basis should not be connected directly to ground, but in that way I have drawn, if R3 is the anti hum resistor. Do you agree?
