Marantz MA-500U X 4; MA-700U X 1 Mono Block Amplifiers

$500 TOTAL for ALL FIVE amps (4 X MA500; 1 X MA700).  Just serviced with a clean bill of health.  Sounds terrific!  Chassis consistent with age.  Not perfect but a solid 7/10.  Will ship in continental U.S.
From Marantz:
Marantz MA-500 The Marantz MA-500 THX Ultra certified Monoblock Power Amplifier measures just 3-3/4” in width, yet delivers 125 watts into 8 ohms. In common with the MA-700, the MA-500 is ideal for creating multi-channel home theater and multi-room systems or for adding additional channels of amplification to an existing system.  High Current Power Supply offers true low impedance drive capability–125 watts into 8 ohms and 180 watts into 4 ohms.  Two MA-500’s can be Bridged together to produce over 360 watts into 8 ohms.  Compact Design–5 MA-500’s occupy the width of a single conventional stereo power amplifier.  Remote Control power on/off and RC-5 remote control interface.
