Amazing Audio Research Reference 2 MkII tube preamplifier in excellent condition. Works and sounds fantastic. Original remote control is in poor cosmetic condition and is not working so I bought a nice aftermarket remote made specifically for this preamp. Tube complement is (6) 6H30, (1) 5AR4, (1) 6L6GC. Many inputs and all have balanced and RCA jacks. There is no phono section even though there is an input labelled phono. 19"W x 7"H x 15.6"D and 31.2 lbs. It is hooked up at my house for demonstration. This preamp was $10,000 new. Great deal for $3300 firm.
