Paranoid on Tube Amp Install

Can speakers cause a tube amp to catch fire? The last tube amp in my system 3 years ago caught fire (just 2 minutes after installing). I always assumed the amp was damaged in shipping. I just ordered another tube amp and I'm both excited and nervous about installing. The speakers are Acoustat 3300 electrostatics and I've been using ss amps since without issue. I really don't want to sit in my chair again, frozen in shock, as I watch a blue flame.

Thanks for any feedback,

Glenn
