contacting Greg
Hi. I've been trying to contact Greg and can not. I can't even sign up for the forum on his site _ keep getting an error. Can someone please PM me his email address. I'd like to talk to him about a 100w kit.
Thanks!
I've built a couple. The use IRFP540/9240 mosfets doubled up (i.e. 4 total) at the output, all other transistors are BC550/560 series. Power is rated at 150W into 8 ohms, not sure about 4 ohms, but feel free to send Greg an email.
