Crescendo HEXAFET
There is one problem with thermal compensation, so here is updated thermal tracking circuit.

Thermal ompensation is an option only for those IRFP's and not necessary for the HITACHI originals, I think.

Of course, but one must be aware of different arrangement of pins (IRFP gds - Laterals gsd).
With few bridges it is possible to use ECW20N20/ECW20P20 for example. Also if interest I can edit PCB .
IRFP's simulates little better, that is why I prefer them .

Hello All.
It's bee a good while since I posted on this thread, I haven't forgotten about it, but life took over and had to put things in the back burner as I have been too busy.
However I am hoping to build a Vero of the my schematic and runs some test hopefully in the near future.

Did I ask you yet whether the copper layer is 2 oz (as with the Elektor originals) or just 1 oz?

Under post 184 you can find latest for given schematic. But there was improvement in circuit, simulates really nice, stable, low thd.
Have a look attached file. Adopted layout also available.
