Good project that involves a 12ax7

[rockgardenlove]

So I have a spare 12ax7 that I took out of my amp, its not dead, I just got some better tubes.  So of course, I'd like to tinker with it


Anyone know of any small single tube circuits that might be fun to build?  I'm looking for something really simple, so I'm not overwhelmed with too much info, I'm new to tubes.  Could I build a booster or something?  I'd prefer to use mostly passive components, I don't really want to add a bunch of transistors and IC's and whatever.

Thanks!

Hi.
Check out the Real McTube, by the late, great Fred Nachbaur.
It uses a 12AX7 (or 12AT7) as a high-gain overdrive.
Not a simple build, but well worth it.
cheers

Looks like a good project.  Thanks. 

Anyone know of anything else that might be a good newbie tube project?

The Shaka Tube looks like fun. Paul Marossy has some great build reports, layouts, etc. at:

Tube driver sounds much better with a 12AY7.

I kinda like the transparancy of unlabeled 12AX7 s.

i have a small bin devoted to unused 12AX7s.

believe me, they just kinda pile up.

i never could get my tube driver running... bad mojo there, or something... spent 10 odd hours debugging!
