Full wave bridge for bias supply- does this look right?

[Chuck H]

Not that I am any real big fan Ken Fisher, but go look at a trainwreck schematic and see what I mean.

I can't be sure why your "not a real big fan of Ken Fischer" but it's good you recognize his better circuits. Obviously your not pigeon holed into one way of thinking. I mention it because the more I design, the more I realize there is a compromise to most choices. When I look at a Trainwreck Express schem, for example, I see balance. And the more I scrutinize it the more I see the checks and balances. Ken may have talked an odd game, but whether intrinsic or edjucational he knew how to build a "guitar" amp.

I designed a similar circuit to the Express and Liverpool amps at a time when schematics for those amps, or even much knowledge of them, was not available. I like my amp better. But that's up to individual players, right? But my design lives in the shadow of the Fischer design because he came up with it first. And though I try to merit differences or otherwise, I still recognize the genius and eloquence of the Trainwreck circuit. And you certainly can't argue engineering much with respect to guitar amps. Ken was, and even now that he is gone, a guy who designed some of the best guitar amps ever made. Like I say, his design is too similar and predates mine, so I am in a tough place. But I still see the eloquence, simplicity and sheer genius of his work.

If noise reduction is what you are looking for, wouldn't two-stage filtering on a standard bias circuit accomplish that?
