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.

I short out the speaker terminals while the preamp volume is up all the way as a demo at shows. In addition, I pull tubes out of the amps **while they are playing** and swap them from one channel to the other, with no ill effect or artifact at all. Is that what is meant by 'bullet proof'? or does that have more to do with what happens when you drop the amp?
Jeff Rowland doesn't want his amps coming back so he builds them accordingly. The Continuum 500 integrated has everything that almost anyone could need as the foundation of a great system.

Buy a pro audio amp. They're designed to take abuse in commercial sound systems and operate in less than ideal condtions of use.

However, I agree wtih Shadome that damage to the speakers is a bigger condern than what amplifer is used.

If you don't trust the operation of the system, then get a pro audio amp with built in DSP. This would allow you to set the amplifier limiters below the point of clipping or below the point at which the speakers would be damaged, which ever is less.

Something like a Crown XTI-1000 probably would be more than adequate power-wise. It is rated for 8, 4 or 2 ohms operation and has the built-in DSP functions.
McIntosh MC 2300 will drive a .5 ohm load (almost a direct short!) all day long. Doesn't even sweat. You should these strapped in mono... The Dead used these amps for there sound system for years.
