Tubenit,
  You one tube reverb guru,do you have a schematic for adding a one tube reverb to a 5F2A tweed princeton?I've done the two tube reverb in the past but it actually had way too much reverb.

 :wink:

By the way,I thank you for your schematics and constant experimenting that you share with the forum.You are number one in my book!

Hey Physconoodler,

I have NOT personally built one but there are some DRAFT ideas in the SCH files here:

I think PRR may have helped with some of this when I was drawing them but can't remember for sure?  I think he advised changing some aspect of it?

Anyhow, here is a GIF of one way that it might be approached. Ignore the James tone stack and substitute a 5E3 type tone stack instead.

With respect, Tubenit

Hey guys,
I know this was posted over three years ago but I just built a 5F2A and wanted to do a reverb add-on.  Did this circuit work for you?  What other modifications were required...if any?  I have room for one additional tube and a small board.  I would also need a pretty small spring reverb tank.

I hope you are still monitoring this.....

thanks for your help!
