I don't know if this has been asked before, but can you use these boards for an aleph J?
The circuit is quite similar. Papa recently provided direction towards using the new
Semisouth JFETs in an Aleph J and I was thinking of giving it a try.

Using the amp single ended on the brianGT boards. Ground the neg input and use GND and + right?

Fran
Yep.

Sure. Just a little leg twisting for the front end semiconductors, and a few jumpers and you have a J. Then you can sub the SemiSouths for the bottom signal fets. You can also disable the Aleph CS circuitry to make a pseudo F3 with dual rails if you would want to try that also.

Default It's working ;)

Hi folks, first picture of my working MiniA
It sounds very nice right now, no hum, no buzz, only music !!!
Ok, I need a good enclosure
I let it burn in this configuration.
You know what ? I feel good !

Many thanks to all of you, Mr Nelson PASS, BrianGT and to other guys who make it real

Glad you got it working. Could you tell me the size of those heatsinks, and approximately how warm they are getting. (Finger test is accurate enough).

Could you describe the sound in two or three sentences?

Thanks Anchan
The heatsinks are oversized 20x10x8cm (L/H/W), just a little bit hot.
I can let my fingers on without hurt, very low temp.
About the sound, very detailed, deep bass, everything is much more "clear".
Running config : UGS preamp / MiniA / Opus DAC and USB, balanced inputs except USB. Previously I was using only a UCD180ST.
As I've got a DCX2496, I'll bi-amp my system, UcD will be dedicated for bass only.
Very rich sound, much more "life" in the speakers, more details in the sound, yes "rich" sensations.
Sorry for my bad English.
Cheers

All components are stock values, but all of them are matched...

Pierre,

if You have briangt boards, see the partslist from attachment below.
However 680pF (c6 in original) not be used, it´s the same as orig. NP aleph5 scheme.

Regards denis

(sorry for my bad english here)
