I forget what I can't remember

Post by xtian »

Recently saw a Fender schematic here, I think, that had

amp stage > treble pot > amp stage > bass pot > PI, etc.

Anyone can help me find this architecture?

The first thing that comes to mind is a Blonde Bassman 6G series

No, that's not it. I think it was a brownface something.

I just went over to the fender field guide site and checked out all the brown/blonde era schematics. They either have the 4 terminal/tapped treble pot or a Baxandall type tone circuit with the exception of the bass channel on the 6G6 amp. Actually its goes triode-bass-triode-treble-triode.

edit
Some of the early (none -A versions)(6G7 as an example) show a standard 3 terminal Pot with the 4 terminal in the later "A" versions.

Well Brown face narrows it down a bit.

Any more clues?

I see it now. There was no CF in the schematic I saw, and the Bass and Treble circuits were simple, Princeton style or textbook style, as Merlin shows on p.196-198, 2nd ed. preamp book.
