Princeton reverb schamatic WITHOUT vibrato?
« 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.

Here's a fresh baked one...
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

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
