Background information<\/strong><\/span><\/div>\n
The Conrad-Johnson Premier 140 is a high-end tube amplifier designed by Bill Conrad and Lew Johnson. The amplifier uses KT88 power tubes and uses carefully selected, high-quality components such as CJD polypropylene capacitors and metal film resistors. The internal wiring is done point-for-point by hand in Fairfax, Virginia (USA). The enclosure is solid, with resonance control in mind. Everything is designed with a focus on musicality and minimal signal contamination. <\/span><\/div>\n
Brand history<\/strong><\/span><\/div>\n
Founded in the mid-1970s in the US by two friends with anything but musical backgrounds. In fact, Dr. William Conrad and Dr. Lewis Johnson were economists by background but with a very strong audiophile passion. Conrad-Johnson products are implemented with simple circuits, but built with the highest quality custom components.<\/span><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
