Up for auction is a used Bryston 4B NPB Stereo Power Amplifier. This amp is used and was pulled in working condition for a recording studio. The amp delivers 250 watts at 8 ohms and is very quiet as it has the side vents for heat disipation instead of a fan. This amp is perfect for your recording studio. The amp weighs 40 pounds, but we are going to include free shipping to the Continental 48 states. When this amp was new, it retailed for $2,300.
