University Model N-3 Three Way Crossover Network for sale, for parts. Unit is all original, and is very clean on the inside. Outside the unit shows some age and blemishes, but it is in good condition with no dents. Both Built-in "Presence" and "Brilliance" controls/potentiometers are in great shape. We are selling "for parts" as the two capacitors are original. We wanted to leave them in and let the next owner make the decision to replace or leave in place. We obtained this unit in a collection of University speakers, and vintage tube amplifiers. It measures 7"x5"x3" and weighs approximately 5lbs.
