Hi,
sounds wonderful, much better than my old Aleph-X. A little on the „sweet“ side, but very fine soundstage with the Viawave ribbons. You can listen for hours.
Only downside in the actual time is a power consumption of 350W per Channel 😱
Actual I have annother project, a complementary X-Amp with „conventional“ Mosfet A/AB output stage and K170/J74 folded cascode input/VAS stage. In comparion the amps sound quite different - some friends prefer the Aleph-JX, some the other amp because of more resolution. Means, in comparison the Aleph-JX perhaps lacks a little bit on the high end. But one friend reported the Aleph-JX is getting better (also) in this regard when the XLR input is used.
For me, I like both, depending on music and mood…
Edit: Lacking resolution is probably wrong, there is nothing missing with the Aleph-JX. The difference more lies in the dynamics of the amps. The Aleph-JX is sweeter, but a little less dynamic sounding.
Regards, J-C

May I share my beast. Hope it is not too late to make Aleph amp nowadays. 🤣 Just finished building Aleph 2, they are all mono block. Take me almost 2 years to be done.
It have 1.2kV tranny feed to 4x130000uf arrange in CRC filtering power supply. the main schematic follow the service manual but I rise up the bias a bit from original since I found the heatsink is not hot enough. 😆
They run well with temp around 55 degree C at the heatsink.
They sing wonderfully, No need to explain how is the sonic character of Aleph amp, thought 😉
Thank you papa Pass for his contribution of all time best amplifier schematic.

You are right. the bolt is isolated by phenolic washer, to prevent transformer short turn.
Wow. Thats a Very Far off the charts insane build. In a good way. 🙂👍
