It's only simulation nothing special about it the Sim really can't put all the measured values in in a few hours.


Well parts N&P 250W coming in a week about from profusion. 102Ä for 3 pairs S suffix, cheap almost.

Are reneas parts as good as the profusion parts for this amplifier?

Renesas does not have double die Mosfet to my knowledge. You need double die Mosfet (2 Mosfet transistors in parallel in same package thus perfectly matched) otherwise the damping factor would be much too low, distortion would rise and the sound would be very different.
The pcb only fits one pair (N and P) of double die Mosfet.

Thanks for the concise explanation Fab and Garborbela.

Thanks
This confirms that Renasas had no double die Mosfet.
From the remaining Semelab, Alfet and Exicon it seems only Exicon is still active for production.
