DIY Tube Buffer pedal?

[trey85stang]

Anyone know of any schematics and layouts for a tube buffer pedal? Ive searched the interwebs and havent found anything. Anyone know of anything? Worst case I would settle for an analouge buffer pdeal.

Have a read of this http://www.tubecad.com/2007/04/blog0103.htm

 

The first circuit shown is probably an adequate start. The value of Rk is dependent on the tube and the HT voltage (which may be subject to whatever transformer you can get your hands on).

 

It's such as simple layout you can probably do point-to-point wiring.

that looks perfect to try, ill have to do some math which isuck at but that is a great link. I plan to use a 12ax7.

Thats kick ass! I will be building this one, unless you have one for sale cheap (i see you're in dallas)

One of the sub-miniature tubes can be powered by low voltage and would make a nice buffer... the 6088 tube comes to mind, and I think you could power it with a common wall-wart power supply. I'll look up the datasheet on it.
