Audio Control Richter Scale Series II EQ Subsonic Filter Crossover PARTS REPAIR

Unit powers on and VU meter bulb is illuminated when the Analyze button is engaged. There are a few scratches on the top of the unit. You should be able to zoom in and see them. Otherwise the unit looks to be clean and in good shape. I plugged in a cd player to the tape in and noticed the VU meter moved a bit at times. I haven't messed with any of the controls so I don't know if anything works correctly. I don't know how to operate this properly and dont own a subwoofer to check. Opene...d the unit up and everything looks clean. I dont know if this unit is working properly so I'm SELLING AS-IS/ FOR PARTS OR REPAIR. NO RETURNS. This unit seems old so don't bid on it if you expect everything to work correctly and aren't prepared to have it fixed, if its even possible. Some info I found online explaining it:Bass equalizer, and it's also an active crossover; the two sections are completely independent and there are different controls and connectors for each. 5-band bass-specific EQ, the equalizer section also features an Ultra Lo Boost (sub bass) and Rumble and Subsonic filters; there's also a tape/source monitor switch and an EQ/bypass control.As for the 18dB/octave electronic crossover section, there's a selectable 100/800Hz crossover frequency point as well as a Lo Frequency Output Level knob.There's also a warble tone generator and VU meter for measuring the warble output.
