Thanks. Will do that 😉

Harrison,take a look at the specs of IRFP9140 is matching much better with the IRFP240
Had a look at it. Its a coin toss. Without need for thermal tracking the IRFP9140 has more current capability. However if thermal tracking is required the IRFP9240 may be better.😉
A design note that uses 22 ohm gate resistors

Another design note that examines the different output mosfets and makes suggestions on gate resistors based on input topology and also examines thermal tracking
http://www.ti.com/litv/pdf/snaa045a
http://www.ti.com/litv/pdf/snaa031a
Both contain pcb examples

The PCBs will be serviced in groups such as 20s so that those who reserved first dont have to wait for others. http://www.diyaudio.com/forums/vendors-bazaar/242311-2diffet-type-2-pcbs-100-a.html. Although am not commenting at the thread am watching it 😉
Kindly make suggestions, complaints, commendations, concerns, worries, congratulations etc😀
Yes the silk will be cleaned up😉
Personaly I don't like the way you located the power fets.What's wrong with Alexmm his layout?
Lets have a little flavour 😎 , some mix and match ?
Hi Alex send me the layout files to info@harrisonaudiolabs.com
As the 100 PCBs will be serviced in batches of 20. Well the first batch can be one PCB and the next can be another 😉

Harrison.

The schematic
The first 20 will print using this schematic and above layout. Time estimate to print 1 month

Let me start a tradition.
The first person to post their complete build of this amplifier and a review of it gets a token of $70.😀
kind regards,
Harrison.

Pleasure 😉. Looking forward to your feedback🙂
Rcvd the packet 😀
Thanks
