Title: Princeton reverb schamatic WITHOUT vibrato?
Post by: 12AX7 on February 04, 2013, 05:02:33 pm

All the PR schematics i look at have vibrato, and i don't understand how the bias is tied into that nor do i want vibrato. Is there either a fender blackface era schematic w/o vibrato, or a custom schematic of someone's design who was looking for the same thing as I am? I suppose i could just eliminate the vibrato, but i'm not sure about how to then implement a bias. I'd rather find a schematic like this then copy the bias off another similar amp's schematic for fear i'd make mistakes with my minimal knowledge.

OK Sluckey beat me to it. 

Joe's Hiway 99 is a real amp that he built.  The other was a proposed draft.

With respect, Tubenit
