Oh yeah!  The Fender Twin Reverb Guitar Amplifier, The Marshall Guitar 
Amplifier and several other less famous tube guitar amps use the 
venerable 12AX7 in the preamp to driver stages.  Most guitar players, 
mahself included, would rather eat lint than play thru a bipolar 
transistor amp.  That's because of the odd-order distortion inherent 
in a bipolar setup.  Tubes are neat, because they exhibit even order 
harmonics when overdriven.

Now the 6GH8 is a hard one.  Haven't seen one in anything of recent 
manufacture.  Maybe someone out there in netland has.....
