Beautifully crafted Mastersound Compact 300b SET Tube Integrated Amplifier. This is the same chassis as the Mastersound Evo 300b which has 2 parallel 300bs per channel. Looks brand new; without a mark. Less than 300 hours of use. The stock power tubes were replaced with better sounding and nearly new Psvane 300B tubes. Also upgraded with new Electro-Harmonix 6SN7s gold pin preamp tubes. Incredibly good looking and great sounding integrated tube amplifier. The remote is perfect. Made in Italy. $10K new. This is a very powerful and dynamic integrated amplifier which produces a large and full sounding sound stage with very strong performance top to bottom. Clearly presents the differences with other than the stock tubes. It is rated at 15 watts class A, no negative feedback and has autobias. This is an extremely fast, open and dynamic sounding 300b amp. It runs very cool, the massive transformers are slightly warm, not hot. I would prefer not to ship as the unit itself weighs 74lbs. I would prefer local pickup in the Dallas area (Anna, TX).
