Up for sale is a used conrad johnson pv6 tube preamp with phono section. UNIT IS NOT WORKING. It is a fairly simple design and I would anticipate a skilled tube repair person will be able to fix it. I will pack as best as possible as I do not have the original box. The PV6 was a refinement of the earlier PV2ar design with improved resistor and capacitor selections. The PV6 used upgraded precision low noise resistors and polypropylene capacitors. The result was superior definition and depth of imaging. The phono section was noticeably quieter than earlier designs.Features:Inputs/Outputs Phono Tuner Auxiliary Monitor and recording facilities for two tape decks with dubbing from Tape 1 to Tape 2 Two main outputs Auto-muting to suppress warm up transients Controls: Selector, Source/Monitor Mode (Reverse, Stereo, Mono)Balance Volume Power Specifications: Gain: Phono Stage 38.5 dB (phono overload 500 mV at 1kHz)Line Stage 28.5 dB Distortion: less than .05% THD or IMD Response: bandpass 2Hz to more than 100kHzRIAA Equalization: +/- .25 dB (20 to 20 kHz)S/N Ratio: Phono Stage 72 dB below 10 mv input Line Stage 84 dB below 2.5 volt output Phase: Line Stage phase correct, Phono Stage phase correctMechanical:14?
