Also now listed my last CJ piece: the Evolution 2000 amplifier.

Up for sale is my CJ Premier 10 preamplifier. Aesthetically, it is in like new condition - I cannot find any blemishes on it on the face or body. Functionally it is beautiful. The volume pots are a little dirty so there is a click when you change the volume, but this is an easy clean. Includes the original manual, original shipping box, and original marketing brochure from when it was purchased. I have NOS tubes I will include as backups, the ones currently inside have 100 or so hours on them. Sold as-is, but guaranteed against DOA. Please add 3% for PayPal. Also check my other listing for the matching Premier 9 DAC. From CJ: The Premier Ten was essentially two mono preamplifiers sharing a line cord and power transformer. Specially constructed controls maintain a physical separation between channels to reduce capacitive-coupling and minimize crosstalk between channels. Individually regulated power supplies electrically isolate the two separate channels. Derived directly from the Premier Seven, the audio circuit of the Premier Ten consists of a single triode amplifier direct coupled to a triode cathode follower. The low output impedance of the cathode follower permits the use of the Premier Ten with highly capacitive amplifier interconnect cables without attenuation of the high frequency information. The zero feedback circuit insures temporal accuracy and spatial detail. The volume control is a 23 position switch selecting among 23 pairs of resistors ­ never more than a single-pair of resistors are inserted in the signal path by this control. The balance control is an 11 position switch that is electrically out of the circuit in the centered position. There are no carbon-track or conductive plastic resistive elements to degrade the audio signal in the Premier Ten. Features: Inputs/Outputs ­ Phono/Aux, Tuner, CD, plus monitor and recording facilities for two tape decks with dubbing from Tape 1 to Tape 2. One pair amplifier (RCA main) outputs Selector, Record (tape out selector), Mute, Balance, Volume, & Power Specifications: Gain: 25 dB Maximum Output is 20 VRMS Distortion: less than .25% THD or IMD at 1.0 V output Response: bandpass 2Hz to more than 100kHz Noise: 94 dB below 2.5 volt output Dimensions: 19" X 5" x 15" Weight: 28 lbs.
