SVP preamps

[deedee]

I've just posted schematics for Ampeg SVP-CL and SVP-Pro preamps in the Technical Documents area.

They are hard to read as they separate the main and valve boards. I'm interested in cloning the Pro, minus the solid-state graphic EQ, and have re-drawn the schematic (attached). Do we have a brave volunteer to idiot-check it? I'll post the PCB design when it's done.

I have to admit I'm not entirely clear how the 'drive' control works.

Thanks for looking.

They are bass guitar preamps. With Valves (or 'Tubes' if you must )
