Introduced in March 1989, January 1992, December 1993
The PV10 drew on the technology of conrad-johnson’s path-breaking Premier Seven
to achieve musical performance beyond its modest price. Both the phono and line stages are zero feedback design. The phono section uses two triode amplifiers separated by a passive RIAA equalization network.
The PV10A revision featured a new line stage circuit based on two 12AU7s. A bit more than a year after the introduction of the PV10A, a line-stage only version was offered — the PV10AL. There have been three variants of the PV10A and AL. The first had the same control set as the PV10, as listed below. The second used a new balance control, with a detented center position that was out of the circuit. The balance enable/disable switch was deleted. The final version of the PV10A and AL deleted the balance control. Aside from these changes, and associated cosmetic revisions, the three versions are all identical in circuitry.
Features:
Inputs/Outputs - Phono, Tuner, CD, Video, and Auxiliary inputs plus one Tape input with monitor and recording facilities. One Main output.
Controls: Selector, Source/Monitor, Balance (deleted in last version of PV10A and AL), Balance In/Out (deleted in later versions of PV10A and AL), Volume, Power.
Auto-muting is provided to suppress warm-up transients.
