Decware CSP2 project help request

I just acquired a CSP2 in "heavy project" condition from a local garage sale. For $100, I couldn't pass it up. It seems to have been modded by the previous owner and I would like to return it to OEM. Looking forward to the resurrection process. Could anyone share a schematic? Thanks in advance.
 
I've owned two Decware amps and a preamp and don't recall ever seeing a schematic?

Decware offers a lifetime warranty. You might contact them and tell them you bought a used preamp and would like to bring it back up to factory specs.

A new CSP2 sells for $1399. I like the CSP2 I have, especially that I can roll tubes with it. Subtle difference in tubes that I can barely hear.
