Furman SP-20AB 2-Channel Amplifier

The SP-20AB Stereo Power Amplifier is a unique and economical 20 watt per channel stereo amplifier. Its toroidal transformer delivers ultra-quiet performance, making it ideal for recording studio applications.

The latter mode allows a power output of 40 watts provided the load is 8 or more ohms.
