Many people acknowledge that this phono preamp was way underpriced when it was sold by Wright Sound. George Wright was a genius. No original box or manual. Comes will all tubes including two 12AX7 and two 12AU7 tubes for the preamp section and one 6EM7/6GL7 (or 6FM7/6FY7) and one 6X4/6202 for the power supply. Local SF Bay area cash sale only so you can inspect and test. Sorry but I will not ship. I want the buyer to inspect, test, listen to the preamp to her/his satisfaction. Has dual gain controls. Can plug directly into amp. The copper needs polishing. Here's more info I got from the Asylum: Phono Equalization is RIAA starndard, accurate within 1.0dB between 20 Hz and 20kHz. The Input Impedance is 47 kilohms shunted by 100pF and the Output is 2 kilohms, nominal (will drive loads down to 600 ohms with minimal loss of output level). Output level is 2 volts peak-to-peak, nominal, when used with MM or High Output MC cartridges. For very low output MCs, a seperate step-up transformer is available from Wright. A two-piece unit (in case you missed that), the peramp itself is is sheathed in clear-coated copper; thus presenting a copper-clad ground plane for for minimal hum--not to mention strikingly cool looks. In addition to the tubes, the pre presents two independent level controls allowing great (and super-simple) flexibility in cartridge matching. The seperate power section is black powder coat with one on/off switch, connected to the pre with a four-conductor umbilical cable. All wiring is by hand point-to-point and the power supply has its own "well filtered filament line".
