This amplifier is in good working condition. Cosmetically it has some marks from being stacked and some age related colouring.
Happily runs four 100W speakers and give a nice warm sound. Given its age, it would probably benefit from a service
The Technics SU-Z11 is a vintage, 4-channel silver-faced integrated stereo amplifier from the early 1980's, often paired with the ST-Z11L tuner. It is known for its robust build, featuring six inputs (including phono for record players), tape monitoring, and tone controls for bass, treble, and balance.
