  1. This beautiful tube headphone amplifier was just built by one of my friends who is one of Bottlehead's lead engineers. I received this in exchange for some work I did for him. In addition to the expert build, he chose a beautiful color for the powder coat, and made the wooden base look very nice. Additionally, he provided a unique assortment of high-quality old stock American tubes (1 x 6080; 5 x 12AU7). Specs: -Input Impedance: 100K ohms -Output Impedance: 120 ohms -Gain: about 15dB into a 300 ohm load like a Sennheiser HD600 -Max Output: about 10V into a 300 ohm load -Power: AC 100-120V -Weight: 5.5lbs -Dimensions: 11.25 x 7.25 x 3.5 (L x W x H inches) $550. I'll pay for shipping; buyer pays for PP fees.
