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.
Inputs/Outputs — Phono, Tuner, Auxiliary, monitor and recording facilities for two tape decks with dubbing from Tape 1 to Tape 2. Two power amplifier (Main) outputs.
