-NOTE: Power button works , but its missing chrome cover as shown

Up for sale is a classic, late 1970s Realistic 31-1987 5-band stereo frequency equalizer. This highly reliable Radio Shack staple uses actual inductors rather than cheaper modern circuitry, delivering an incredibly warm, musical tone control that is excellent for tailoring a home stereo or managing vintage vinyl transfers.

• Controls: All sliders move smoothly and function quietly across their full range.

Specs & Features:

• Design: 5 frequency bands per channel (60Hz, 240Hz, 1kHz, 3.5kHz, 10kHz) for independent left and right adjustments.
• Control Range: Powerful ±12dB boost or cut per band.
• Connectivity: Simple stereo RCA inputs and outputs, plus a tape monitor circuit.
