Introduced in July 1988, March 1991
The PV9, also an all-tube zero-feedback design offered a step up from the PV8. The basic audio circuit of the PV9 is essentially modular, built from individual gain blocks consisting of a triode amplifier direct coupled to a cathode follower. The phono stage consists of a gain block, a passive RIAA network, and a second gain block. The line stage consists of a single gain block. Both phono and line stages used pure polystyrene capacitors exclusively, including the large output coupling capacitors.
The PV9a substituted 6FQ7s for the cathode follower tubes for lowered source impedance.
