PHYSICAL CONDITION: Very Good- These pair of mono power amplifiers are in good structural condition. They both have tiny minor scratches in various parts of the units. One of the units is missing all four rubber feet.

The units also look very clean and in near excellent condition. Overall, this set of amplifiers look like they have many years of amplifying ahead of them. They are in very good condition.

WORKING CONDITION: Excellent- Both of these amps are working great! The input select switch between unbalanced RCA and balanced XLR/TRS input makes a little crunchy noise when switched but that's the only flaw found with these amps. They're loud, clean and very powerful! Overall, in excellent condition. 


UNPACKAGED DIMENSIONS: 19" x 5.5" x 16.5" Each
