    For Sale
    Selling a freshly minted Bottlehead Crack OTL headphone amplifier with the optional Speedball upgrade.  This is the latest Crack v1.1 model with the universal power transformer so the mains voltage can be set for anything from 110v to 240v covering just about anywhere in the world.
    Chassis plate and transformer bell are painted a hammered effect metallic brown with a satin black power transformer with all black mounting hardware.
    The wood base has been dyed with American Walnut and finished with multiple coats of Danish oil and wood wax for a smooth natural finish with bronze edge protectors.
    Circuitry has been assembled with Cardas silver solder with the optional Speedball constant current source upgrade which lowers the distortion and noise floor for a cleaner more detailed sound. The output capacitors have been upgraded with Polypropylene Film for greater transparency over the stock electrolytics.
    Tubes supplied are a Baldwin branded Sylvania 12AU7A input tube, and a Beckman branded RCA 6080 output tube.
    The Bottlehead Crack is suitable for any high impedance headphone of 200ohms of higher, and is renowned for its synergy with the Sennheiser HD600/HD650/HD800 series headphones.  Assembly manual and power cord included, price excludes shipping to UK / EU which is approx €50.
