Help on Marshall AVT150H gone bad..please

Ok we were trying out the AMP without no cabinet, we plugged a headphone on the headphone jack and its sounded amazing but we didnt have a cabinet so we tried plugging in to a crate combo amp, so we did AVT150's speaker out -> input of the crate combo amp 65watts, it sounded great so after 30mins or so i decided to power it off, but when i hit the combo amps power off switch the light of the the marshall AVT150 went flickering an i think i heard a pop sound after which the amphead gave off a burnt smell, so we opened it up and saw the fuse was burned out, my question is, is because of what we did is there any chance that we fried the amphead? or we just need to change the fuse? also where will we get a replacement tube?

Please advise..thanks

Pop with a burned smell? Not good. Something may have popped that caused the fuse to blow. Replace the fuse. If it sounds and doesn't blow again you got lucky. If it blows again....

If a resistor or capacitor popped and sprayed microscopic electroconductive dust over the board the board could be FUBR'd.

you would have been better to disconnect the speaker on the combo and wire a jack plug to the connector, never a good idea to use the wrong kind of input signal for any amp, i blew a fender guitar combo by using a bass through it for 2 and a half hours, i learned the hard way too lol
