Damn greenhorns...Meters… everyone’s going fancy pants these days. I don’t even have an LED. Need to pimp my amp…
Yes that’s correct, but that’s not really the reason I haven’t done it yet. You see the wife has problems with this hobby allready. I am not sure that a backlit fallos on the faceplate, jumping with the muzak, is going to helpDamn greenhorns...![]()
Mighty succeeded in a dead stable incarnation of such a circuit. Check his blog!Or pointers to the Aleph-X? I've not found a really good guide for it. That project still seems a bit raw.
Thanks for askingPeppe
Any better these days, I hope ?

Hoping for your good health, Vinz.
Here, Covid is getting the best of me and the whole gang. Luckily slowly getting better.

But maybe the up and coming XA252 could be something for you?

.... my old Yamaha NS A-780 integrated with these LRS and its a better pairing in terms of delivery. Its not that great of an amp, or at at least it didn't really like 8ohm loads...
Biasing the Aleph J higher from nominal 400mV with a sitter to say 500mV will achieve what?
Its sounds otherwise decent. I believe it to be ok, but lacking a little dynamic impact (within the bounds of ribbon speakers), so it struggles. The Yamaha does much better in this regard. My vintage A760 is a first run unit, which has a passive pre section, dual mono power and notably contains a well implemented PS noise reduction circuit that Yamaha was sued by Carver for. Fun.Besides more strain on the PSU and therefore more ripple/noise on the rails, and more heat on your sinks, you will achieve a slightly larger class A envelope. But that does bot nescessarily mean a large inmproment wrt clipping levels (maths you must ask others about).
What this goes to show is that even a well constructed and very stable single ended class A circuit will struggle with current hungry ribbon speakers. A good test, it will help you choose future amp.
But that aside: how did it sound when not clipping (low levels?)?
