Conrad Johnson PV8 Preamplifier
This Item is from the estate of the late great musician “Lorin Levee” the Principal Clarinetist for the Los Angeles Philharmonic Orchestra. Mr. Levee played for the Orchestra from (1971 – 2012). He was prominently featured in many of the Ochestras recordings, including the Rachmaninoff 2nd Symphony conducted by Simon Rattle & Gerswin’s Rhapsody in Blue conducted by Michael Tilson Thomas.
The PV8 superceded the PV5. It was the first all-tube zero-feedback design from conrad-johnson. The basic audio circuit of the PV8 is 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. These stages use polypropylene capacitors bypassed by a polystyrene capacitor for the output stages. Even the main dc power supplies used polypropylene capacitors - there are no electrolytic capacitors in the audio circuits or their related power supplies. Paralleled triode sections at the phono input yield nearly 3 dB improvements in the signal to noise ratio over a single input tube (as used in the earlier PV5).

I would rate this a 9/10 if it wasn't for a`small imperfection on the front right face plate small imperfection on right side middle / looks like a smug makes it a 7/10.
