PLEASE NOTE: Vacuum tubes are uninstalled for shipment and must be installed by the buyer upon installation in your system. Unlike many tube amplifiers, these tubes require soldering the wire to the top cap of the power tubes, and reinstalling the tube cages from the bottom of the unit. Please ensure you are comfortable performing these tasks safely and properly or be prepared to obtain assistance from a trained professional.
"Designing our single-ended amplifier has proven far more difficult than I first imagined. The first major problems were the reliability and quality of current production triode tubes. Most of the fashionable tubes tested (300Bs, etc) offered very poor performance. Driven hard in single-ended mode, these tubes give 10W, but with poor reliability — only a few hundred hours’ use — and diabolical performance. I wanted a minimum of 10W of clean single-ended power, plus a good few thousand hours of valve life. Surely no customer wants to be spending hundreds of pounds on new output valves every couple of months" - Tim de Paravicini
"the 859 is a true Class A design delivering 13W/channel, both channels driven and over a power bandwidth of 20-20kHz, +/- 0.5dB. Frequency response is 5-50kHz @1W, sensitivity for full power is 200mV, and distortion at full power is <2% @1kHz and <5% @ 20-20kHz." - Home Theater Review
