Peter Daniel sells PCBs for Aleph J-X. You need to buy two Aleph J boards per channel and Peter supplies the daughter board as well to connect them up to make a X of that.

Check GB of Peter or email him.

With those boards you can get any suitable power output, just adjust voltage rails accordingly.

The Aleph-X and it's variants like the Aleph-JX are something for the more adventurous as it usually requires more experience in building amps. The AX was not published by Nelson, it was originally a prototype developed by Grey and does not have the perfect level of maturity like amps build in series production (or the ones published by Nelson).

If you're not sure how to downscale the 100W amp, you might be better off building something better documented (AlephJ, F5).
