If you can't design your own, you would be better off buying Rod's PCB. With high power amps, layout is critical. It can take three or four versions of a PCB to get it right, and so will cost more in the long term. Anyway, Rod needs all the financial support he can get to keep his site running, and for providing that resource, he deserves our respect.

I agree, support Rod, he produces fantastic PCB's, and offers assistance as well if you buy from him, I did.

You can use MJL21193/21194 if you want, or MJL3281/1302.

The PCB layout is Rod's proprietary work, if you want it you'll have to buy a PCB!
