Roost amps?

Hi, I'm looking for some more infos on Roost amps. Specifically looking for a schematic of a Roost SR100. Any help is highly appreciated.

I found this site: Link Removed but the links to the schematics are dead. No idea if sending a message to admin will get any response. The site may be an orphan.

I also found a very old reference on in this thread: Schematics

If the forum is active, you may be able to sign up and ping the person who originally posted the schematics.

Other than that, I know they are somewhat related to Hiwatt amps. Perhaps some of the vintage Hiwatt schematics will be useful: MHuss Hiwatt Amplifier Pages - Tech Info

You might also try the various FB sites affiliated with Roost amps, for example: Roost Amps - Best british Tube Amplifiers since 1970
