Ohhhh!!!!! I see - bit of fast action on the forum as well as on track!...Put me off track..but I am old, slow and over here!😀😀😀😀

Also - good buddy's GF 'n soon to be SWMBO iz big time car tire rep so wuz in winners circle getting picture taken with Dario and little red car. Sigh - it's a hard life having to hang out with the race car driver and owners crowd......

Have you had a chance to build anything else for comparison?
I am thinking of building up one of these but possibly using laterals.

In addition, I have built F4, ZV9 and a secret wonder-weapon.
(thanks to Generg and Papa.)
F4 does not play without proper pre-amp.
With lateral FETs now I'm not built yet.

It is time for me to start getting serious.
I don't think anyone has done an Aleph with laterals so I suppose someone has to do it.
It may as well be me.

Forgive me, you know my English is terrible and I do not understand electronics.
But something I read as if the laterals were not really the Aleph topology is chosen. Because VGS lover?

Yes of course, laterals have lower Vgs, but I don't see why you could not use them.
Just need to adjust the circuit slightly to accept them.
Still probably use IRFP240 for current source.

I will attack it and let you know what needs to be done.
Just need to finish my speakers first.
Hopefully have the speakers finished in the next 2 weeks.

done several times
even by Mighty ZM
but you probably know that I'm always trying another one , in same test bed ........ so I don't have it
take xconductance in account , Vgs difference is irrelevant , as long you have OLG under control
conclusion - Aleph with laterals - boiled water .......... and difference comparing to IRFP150 isn't worth any hassle
but - Jfet FE is very well worth the hassle
NB- one IRFP150 instead of 2 IRFP240

OLG should be lower with laterals
What does boiled water mean?
EDIT: Even though you have already done this I would not mind doing it myself purely to satisfy my curiosity and possibly learn something.
Besides that I have a tonne of laterals lying around.

use lowest source resistors you can (in output)
use more output pairs
squeeze as much gain you can from FE - minimal source resistors , same as paralleled jfets (as in Aleph J or Mighty ZM's Mighty Babelfish J
