SM said transistors were far too noisy to use for prototyping, so I figured, "let's use tubes, he did say to use them, right?".  But, I don't know the first thing about electron tubes!!  I've never seen one, let alone use one.  Right now I'm looking on TubeDepot.com for some tubes, and I don't know what I'm looking for.  Ugh, frustrating!  Anyone with some tube experience here?  I could really use some help!  Thanks!!

I think that the majority of people here don't know how to use them either, you are not alone...................

The 12AT7 looks good for my design, I can use either 6 volts or 12 volts for the heater, I think I'm going with 12 for now.  It seems weird using a transistor to switch a tube on and off rapidly.  Oh well, in SM we trust :D  Heh.  I hope these tubes work well.

wouldnt you want to be making a tube oscillator circuit
maybe a VCO ?
i guess you would need 3 of them.
look for some micro-tubes.
they will be small enough to fit in the center of the ring.
