Here to answer questions? Or should not be knocking on the closed door?

You need to ask 1843, as it's his design.

The PCB I posted is a Whites Surfmaster (unfinished) clone.

When it is finished, I will post the PDF and the Protel format of the PCB here.

Hi Sean, not finished yet?

If I connect the Base and Emitter of Q9, It smokes everywhere, And I dont know why.

Hello guys,

I know this is an old thread, but I'm really interested in this scheme and would like to ask you a question:
What is the purpose of d6, c10 and r13? Is this to shift the voltage level from -/+5V to 0-5V?
I want to experiment with DSP but don't know how to interface the ADC with preamp. I'm pretty good at coding but really bad in electronics, so I will appreciate any advice regarding interfacing the preamp and ADC. I won't do any commercial stuff, just doing it for my own fun.

Thanks in advance!

Nevermind, I found the answer by myself.
Thanks to the hundreds of "knowing" people who helped me...
