I built this preamp recently, and its in very good cosmetic and working condition. It consists of a custom aluminum chassis from Par-Metal, a custom faceplate from FrontPanelExpress, and PCBs I designed and had made by ExpressPCB. It uses matched genuine Toshiba FETs (2SK170 and 2SJ74). The power supply regulators are LT1033 and LT1085 (dual mono), and it uses an oversized Plitron toroidal transformer. The preamp includes front panel switching as follows: Volume (using an Alps quad pot), Input selector (labelled Tuner, DAC, Phono and Tape), Mode selector (with positions for Stereo, Left only, Right only, Reverse), and a Meter Gain switch with settings of +10, +5, 0 and -4dB (the latter for studio level reel to reel tape decks). Note that the front panel Mode switch is also labelled for a Mono position, but this was not implemented. The VU meters are genuine vintage Dixson VU meters, driven by a buffered circuit cribbed from the Levinson LNP-2, and the meters are illuminated by overhead LEDs. There is also a 12 volt trigger output on the rear to remotely start a power amp. The XLRs are all Neutrik gold, with two sets of balanced outputs. The balanced Phono input also has a switchable unbalanced RCA input (Vampire gold/Teflon), and there’s also an unbalanced RCA main output to drive a subwoofer. Working fine, but sold as-is, buyer to pay actual shipping costs using their choice of carrier. Asking $1,250.
