bullet proof amp


I need a bullet proof amp to put into my shop where many people could use it,some not so careful, that can drive 4 speakers. vintage preferred.
128x128mbkpao
Aragon 8008 - I heard someone say once that you could hook it up to your curtains and get sound.....
Why would anyone put amps like those (Aragon, Mac, Bryston, Forte, et al) in a "shop system" where it's going to be abused by the environment? Not to mention who might be operating it.
because I will be the one who will be listening most of the time and I want at least a decent sound system.
and I can afford it

Used Plinius SA-250MK4 is as bullet-proof as it gets, excellent sound and will drive whatever you care to feed it.
