I received a sales flyer today advertising vacuum tubes for sale! Remember when you could 'shotgun' your TV with 6GH8's and 12AX7's ? Does anyone out there know of any equipment manufactured within the last 20 years which uses these things ?

Musical instrument amplifiers, notably Fender and Mesa Boogie still use 12AX7's in their preamp stages and 6L6's in the output stage. Most of these amps now use silicon rectifiers, although some guitarists claim that 5U4's "sound better". John Reynolds NZ7J Tektronix TV Division Beaverton, OR

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..... -- Clark (Mack) McDonald ARPA: mack@frc.ri.cmu.edu Field Robotics Center Carnegie Mellon University (412) 268-6555 Pittsburgh, PA 15213-- Clark (Mack) McDonald ARPA: mack@frc.ri.cmu.edu Field Robotics Center Carnegie Mellon University (412) 268-6555 Pittsburgh, PA 15213
