This an excellent pre-amp. The sound is beautiful. I purchased this on Audiogon 1/7/10 to get an idea of the sound. I sent it back to the DR. for a check up and while there he added a second input( where the selector reads HT bypass is the second input). You may or may not have a use for the line router to add 4 more inputs. I purchased it as a 3 chassis unit so I'm selling it that way. I love the sound so much I purchased a custom Line 2A SE pre-amp as I don't use phono.Included are the stock 12SN7 Sylvania tubes, one pair GE 12SC7 tubes(phono stage),one pair Sylvania 6SN7W tubes,a Sylvania JHS-CHS 6X5GT rectifier tube,power cord,umbilical cord,owners manual and a HiFi tuning Silverstar fuse in the proper size and rating,as well as the stock fuse. $650.00 all in( shipping,insurance and Paypal!!) Below are the specs:
* Low distortion NOS octal tubes (2 x 12SC7, 2 x 12SN7GT switchable for 6SN7GT).
* Hybrid passive/feedback RIAA equalization.
* Low impedance cathode-follower outputs.
* Two line inputs with 20 dB gain.
* Parallel line outputs for bi-amping or driving a headphone amplifier.
* Source selector switch, volume, and individual channel level controls.
* All point-to-point wiring using silver-plated Teflon wire.
* Includes PS 2 power supply.
* High quality components are used throughout: precision metal film resistors, Auricap and Black Gate signal capacitors, and plastic element volume control.
Specifications: Input resistance: phono - 47 kOhms, line - 500 kOhms. Output impedance: less than 500 Ohms. RIAA equalization: within 0.5 dB 20 Hz–20 kHz. Gain: phono - 50 dB at 1 kHz, line - 20 dB. Line input frequency response: 15 Hz–130 kHz -1 dB. Hum and noise: phono - less than 1.5 mV for gain of 40 dB (60 dB below 1.5 V output), line - less than 0.5 mV for 20 dB gain.
