Bottlehead Crack OTL Tube Headphone Amplifier with Speedball Upgrade - Brand New / 5 Extra 12AU7 [Expired]


no longer for sale

This beautiful tube headphone amplifier was 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). Personally, I think it is the best bang for your buck headphone amp that you can get. It pairs perfectly with high impedance headphone amps like the Sennheiser HD 600 or HD 650, or even Beyerdynamic DT880 600 ohms. You will immediately feel the sensation of a nice tube amp when listening to this amplifier as it delivers an incredibly clear but very dynamic sound. 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) Given that this is slightly more unique than your average build, I'm asking $499.95. Buyer pays shipping and PP fees.
