Vintage Audio Control Equalizer Model 520 Series B

You are bidding on an Audio Control Equalizer Model 520, By Audio Control. It is in very good physical condition out of a smoke free home. I don’t have any way to test it, even power test because it doesn’t have anything to light up. I have several pieces from the same estate and that work just fine so no reason this one shouldn’t either. Item sold as is like all auctions so email with any questions. Thanks for looking.
