Exclamation Marshall valvestae 150 burnout

I have to of these amps in a rehearsal room I operate.
Both are great but today one started to smoke and died.
What is the likely cause of this?
I am new to amp repair but need to learn to manage the equipment better on my own.p

Poison, I've moved this to a thread of it's own. As far as I can tell these Marshall amps are solid state emulating valve sound so I have left it here in solid state.

AFAIK it has a tube pre-amp and transistors in the power amp.
