Dumble/Brian May treble booster schematics?
Does anyone know where I can find Dumble amp schematics, and/or the treble booster Brian May uses (I guess Roger Deacon, Queen's bass player, built it)? I believe there's a file floating around somewhere, but I don't know where.

R.G.'s site has the Ra****** treble boost schematic. The Ge unit sounds very good and it can also be built as a Si based unit very good as well the Ge is the "more correct" version. There were Dumble schematics.
Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.
