I bought mine new not long after it was released in the stores in the early 1980's . The amp performed faultlessly for many decades and only recently needed to be repaired , good going for an electrical device that was used most days for over thirty years to have lasted so long and will used again for a long time to come .

Got mine for 100 used, and it served me really well. Loved having the 5 band equalizer without buying another component. Sounded pretty good, and the VU meter is a nice touch. These early 80s marantz all look cool as heck too!

Do you know how to get a user manual ?
