Introduced: PV1 in 1977
Introduced in 1977 by Bill Conrad and Lew Johnson, the conrad-johnson preamplifier, later designated the PV1, was an important factor in the revival of the preeminence of vacuum-tube audio components in high-end audio.
Already with their first product, conrad-johnson was emphasizing the critical importance of the quality of component parts. The original PV1 literature noted the use of "metal film resistors and polyester and silvered mica capacitors". Critics of the day regarded the PV1 to be one of the best sounding preamps at the time, particularly noting its natural reproduction of musical harmonics. Built on a rugged chassis with a robust power supply, a great many PV1’s are still in use today!
