Hi formula 22
I don't made tis amp because I prefer BJTs as output devices, lateral MOSFETs are very difficult to obtain and there are a lot of fakes, vertical MOSFETs like IRFP240/9240 are designed for switching applications.
I'm building my own 25W class A hybrid, see in the forum for schematics.
Best regards
Johann

Hi Johann!
Can you recommend a good quality one preamp with tube/valve ECC82 or PCC88 (schematic or project).
Thank you for your cooperation.:)
