Tube-like low power amp (MOSFET Ruby?)

[brett]

Hi.
Would I be right in thinking that somebody familiar with mosfets could design a small (2 to 5W) amp with tube-like overload tone?  Maybe based on a 12V 1A wall-wart supply?

I suppose that the pre-amp could be as simple as a CD4049UBE.
It should be very economical compared with a real tube amp.  

There's a couple of low-power FET amps on the web which might do the job.  From memory, they're based on IRF510s.  Any comments?

Anybody?

this may not be the same thing...but you could try this little amp i designed....8 watts.

That's pretty cool, casey.  I'm looking at doing a similar thing with one of the amp emulation circuits as the preamp.

casey, on your schematic, are the resistors in k ohms (10k, 39k, 1k) in the power amp section?  There's no indication.
