Fisher Model R-200 AM-FM Stereophonic Tuner




This is an early 1960's Fisher Model R-200 AM-FM Stereophonic Tuner that uses vacuum tubes. My unit has a wooden case. The tuner receives standard broadcast AM band and the broadcast FM band. The tuner incorporates the Fisher MPX-60 stereo multiplex decoder unit.

Features of this tuner include:
Two-position sensitivity control - Normal and Local
Three bandwidths for AM reception - Sharp, Normal, and Wide
FM (monophonic)
FM Automatic (automatically switches to stereo when the stereo pilot is received)
FM Stereo (always in the Stereo mode)
FM Muting (with variable mute level based on signal strength)
FM Stereo Filter

There are three colored lights in the center of the front panel. These lamps from left to right indicate, FM mode (green), Stereo (yellow), and AM (red).

After I aligned the tuner, the tuner works well on both AM and FM. I have the tuner mated with my Fisher Model X-100 Stereo Master Control Amplifier. A picture of this combination is shown below.
