The Specimen Line Pre-amp provides a rock solid foundation for a larger sound system. This preamp unit uses a famous old twin triode, known under different hats as the 5998, 6AS7, 421A, 2399. Two 6L6s are used as a constant current source load. The circuit allows four different line inputs to be conveniently switched in front of any of our power amps.
It provides a voltage gain of 1.92 to 3.96 depending on which tube you use, to provide a more solid foundation and a bit more volume from the power amps. A 19″ deep shelf or table surface is ideal to combine Specimen Products whole line of audio components.
