Boulder 3060 Stereo Power Amplifier

Production of the 3060 is extremely limited and every unit is built to order Each amplifier is shipped with a machined aluminum and polished stainless steel base that is cut to match the footprint and casework angles of the amplifier 60 bipolar output transistors per channel mean unmatched control of any loudspeaker system All assemblies are completely designed, manufactured and hand-assembled at our facility in Louisville, Colorado Contains four (two per channel) of Boulder's highest performing gain stage, the 99H 48 massive filter capacitors are part of an ultra-responsive, low-impedance power supply 900W per channel power output into any loudspeaker load Bias operation is Class-A to full rated output power and managed with an analog circuit that minimizes heat and power consumption Five power transformers, housed in machined cases and potted to absolutely eliminate any noise, vibration or hum
