Schematic needed for circa 1985 tube preamp kit

[KirkinSanDiego]

Hello,

I have a hand bulit tube preamp with phono stage in need of repair. My tech Mike Z. needs a schematic to fix it. I have taken pictures and will post with.

This was a DIY kit from Glass Audio circa 1085. Possibly Borberly design.

The circuit board says Old Colony Sound Labs 1985

Any help would be appreciated! You can email directly to painfixers@gmail.com

Thank you for any leads on this. Kirk
