The PV2 was a refinement of the PV1. The PV2 offered a similar circuit with the more linear 5751 substituted for the second triode in the phono stage and 12AT7s used as cathode followers for lower output impedance. The PV2 was constructed on a single main pc-board, eliminating the cumbersome wiring harnesses of the PV1, and assuring unit-to-unit consistency in production. The PV2 maintained or improved the parts quality standards established in the PV1. A muting circuit was added to mute the turn-on and turn-off surges associated with tube preamplifiers.

The PV2a revision entailed eliminating a coupling capacitor from both phono and line stages, resulting in significantly improved bass performance. Re-trimming the phono stage resulted in improved linearity and even closer RIAA tracking, further improved by use of 1% tolerance capacitors in the equalization circuit. The input tube for the line stage was changed from a 12AT7 to a 5751. Coupling capacitors were upgraded from mylar to polypropylene. The PV2ar further enhanced this model by a number of parametric changes aimed at improving high-frequency transient response.
