no sorry , intendevo dire circuiti tipo tpa questi di ultima generazione , gia schermati , solo da ordinare

@andyfierman No those are terrible.  Class D has come on massively in last ten years so do it properly, preferably with a DSP core and decent output transistors. For example [https://www.infineon.com/cms/en/product/power/audio-driver-ics/class-d-audio-ics/](https://www.infineon.com/cms/en/product/power/audio-driver-ics/class-d-audio-ics/) STM and NXP also have much newer designs.   You can do Class D in discrete but only by putting it in a steel box and ignoring half of the EMI and PFC regulations (as most high power amp manufacturers do !) :-)

grazie molto utile

Thanks for the advice Mike, The only Class D amp I ever tried to design and build was something only slightly ahead of the Sinclair X10... :)

Hehe - you're as old as I am.  I blew several of those up before getting a refund.
