Friedman Twin Sister Circuit?

[Chalky]

I bought a Twin Sister, great all-round amp, currently my ‘go-to’ .. hitherto i have always had a schematics for my amps (Marshall, Fender ..) so i can understand a little about the amp before trying to troubleshoot when something goes daft, but on this occasion it seems difficult to obtain for Friedman. The links embedded in this string do not allow access to the download.
Does anyone know how to obtain a schematic for a Twin Sister or Dirty Shirley ..or is it a deep military secret?

If you go to the thread linked on the first post you'll find the schematic at the bottom of the first post.
