Yeah, thanks for the tip. Its correct that the silkscreen is printed wrong. An irf9610 in that spot needs to be turned 180 degrees. Since I used BC560c in that position, I was careful to make the right connections. I think I got it right at leastdr.strangelove3 said:
Its easier to get an overview over the "Kari board"s, than it is the green Rev1 boards, which has some more options and jumpers.ZM, I also match the source and drain resistors for the input pair.
Also the source resistors for the IRFP's will be matched. There will probably be some tweeking of the McMillan resistor value.
Here is a closeup of T3, I think you can make out the connections from that.

nice to have you to do the drek
any progress from ystrdy 0845 ?
blue ones will be in mail probably tomorrow
I consider it having all the fun
Regarding progress, not much except for the two very tightly matched sets of IRFP240's on the pic Did some matching this morning and had these two superb tight sets out of the effort. (Together with matched sets for two F4 monoblocks, both N- and P-channels. 
)My plan is to build the Babbel-X into the case where the Babbelfish is right now. Since a guy borrowed it, I will have to wait until I get it back. I cant blame him for not wanting to return it
The beast sounds great I am also waiting for the trafo to show up, since I didnt have a 2x12V on the shelf. All in all, we are on track, though. Looking forward to see the blue ones. I might frame then and put them over my workspace for inspiration

Hmmm......
I do have an inventory, and I suppose I could consider selling
some to you, Zen Mod, assuming that it is a not-exceeding-cost-
plus-pizza-and-beer effort.
(you will notice that my terms are slightly more generous than
DIYAudio criterion of pizza only)
one time only deal
/Pass/: Is drinking Bordeaux on a Friday night and is not only in
a generous mood, but can't remember the exact syntax that
Halojoy used for his sign-off.
