"blew the outputs up in flames????"
Is this a solid state Marshall?
All of the Marshalls that I've dealt with had tube outputs.
If it IS a solid state output, you probably damaged the speaker voice coil.
A single shorted output will put DC out on the speaker. I ALWAYS remove
all speakers
from solid state direct coupled outputs untill I know what's going on
with them.
