Rotel RA-311

 Here is the best example of Rotel's cost-performance outperformer. RA-311 is a new and very versatile stereo pre-main amplifier that let you handle all kinds of program sources. Besides record player, note two tape recorders you can operate and with dubbing, too. And yet another input for an additional component, not counting one for tuner. All can be simply and smoothly controlled by this amplifier's amplr 20W + 20W RMS continuous power both channels driven at wide frequency response and negligible distortion, along with other efficient controls and switches.
