Glad to see my Aleph-X web page is of some use still. The project is getting a bit old (15+ years), but it's still a nice amp.
even more glad to see thet your famous site is still there and you are sharing all your experience with us 😉
THANKS!!!
regards Joachim

Funny thing about those experiences - they all came from this forum 😉 Plenty of people here have helped me learn, so I'm just passing things along.

Funny you mention this - I was just updating the section of my web page for absolute DC offset and the servo to be a little cleaner.
The result is that with the servo, offset behavior is clearly improved. My output mosfets are mounted across several sinks and they now warm up much more evenly than they ever did before and absolute DC offset decreases much faster than it ever did before. However, absolute DC offset behavior does not stay fixed at zero volts. It starts at about 6.0v now (was more than twice this) and comes close to zero volts within 30 minutes (used to be more than an hour). Guess there are just too many variables at play in my configuration.

uupss... didn't see that until now
I bought my PCBs here around. Someone has them left over.
There is another source somewhere in Croatia.
I did not know if those PCBs are somehow 'official'
Therefore i asked the seller by mail and did never get an answer.
Maybe no answer also is an answer.
Bying in China is a no go i think.
So you may better ask here or in local forums related on DIY amps
good luck, Joachim
Official Aleph-X PCB
Joachim,
The PCBs you have are the official ones, designed by member hifiZen. You can find all pertinent information in the thread linked below.

Findus,
In my enthusiasm for the Aleph-X project and all its possible variations, I overestimated how many boards I would actually need and bought too many. I have unused Aleph-X PCBs from the official release, as linked above. If interested you can contact me using Private Message.

I know 😉
I wrote that i have got mine from here.
ANOTHER source is.... 🙄
But, don't tell it, i also have a set from Croatia 😱
Later on i noticed that there is some troubble with the rights.
I got them for cheap. But i'm not shure if i should use them.
Maybe it would be ok to make a donation to diyaudio to make it somehow 'legal' 😉
