Cornford RK100 Richie Kotzen Schematic

Post by Turret »

Hi there, 3th time poster, long time looker

There was a tread related to this amp, but kinda gone wrong

Here's my attempt, tracing was done from pictures provided by GJonesy at SLOforum (cheers if you a member here). Since I never seen nor touched this amp in person I can't be sure how accurate it is. Still few things missing, but at this point I have no way to do any more work with it

Hope you like it
Cheers

It will be interesting to see what Paul from Conford Amps will come out with after his restructuring. :)

I'd have to say that is a very neat looking layout. It is very clean, almost reminds me of a Hiwatt. From the clips I've heard, it sounds pretty good as well.

I've been seeing the old Cornford threads popping back up lately. Some time last year all the official schematics were leaked on a German forum. Here is the rk100.

Cheers!

Update: Id posted the schem, but then wondered if I should. Martin Kidd has moved on, but I'm not sure about ethics relative to Paul Cornford. LMK if I should post. My thought is that this particular amp is highly unlikely to see production again, but maybe...

Ok, thanks for the heads-up. I'm glad I pulled it then. As a hobbyist and seeker of knowledge it's invaluable to me to be able to study schematics, compare and contrast, etc. it's enjoyable to me, even though I have no formal electronics training. I just like to know how things work. I've built a few amps, pedals, and guitars, but there is no scenario where I can picture myself in a commercial amp building endeavor. That said, I get that the Internet is full of people with less moral fiber who would absolutely look to capitalize. Thanks again for chiming in.

Fwiw, I think Martin Kidd is a fantastic designer and by all accounts an exemplary human being. All the best to him.

Also, I'm lusting after a couple of his new amps. :)
