This is an amazing piece of gear. Comes with 2 Electro Harmonix 6SN7 tubes for the outer positions and 2 vintage Sylvania 6SN7 GT's for the inner positions. Tubing rolling in the outer sockets doesn't make much difference. Here are the options, making the Reference Pre so special. Sonicap Platinum bypass caps, 5 Bybee purifiers--3 in the power supply and 2 on the analog outs--and 4 Herbie's Peek tube dampers. Sonicaps and Bybees were all installed by Gary Dodd. Easily bested the Modwright, Manley, and Van Alstine preamps I owned previously. Why am I selling it? Because I don't have the room for the preamp and the power supply. Preamp is in solid 8/10 condition w/ original packaging and manual.
Retail was around $6000, looking for $2000. Will consider trades for a high quality one box preamp.
PM for pics. Local pickup, or audition, in Seattle, WA.
