Hi!

The first sheet I uploaded had reference for capacitor C7 duplicated in error which I only noticed after I'd sent it! "C7" in series with the "PREAMP GAIN" pot RV1 should read "C8" and "C8" (1n) between T2 and T3 emitters should read "C9".

I'll upload a revised sheet adding the circuit functions, voltage readings and the preamp PCB done in a lighter background tint after the remainder is completed!
