Ashdown MAG115 smokey!

[Lewbass]

So My OTB 500 has now be repaired. But my cab is still KAPUT.
I'm no whizz with technical stuff, but I can solder and fix things if I know what is wrong.

Here is what happened.

My head had a PCB issue, it seemed to just dump ALOT of of energy (or what ever) straight into the my cab.
When i hooked my Amp and Cab up the problem happened straight away, no sound was made, just a burning smell (like the smell of burning wire casing) and then the smoke.

I am hoping this is not speaker related, and just some kind of connecting wire and/or fuse problem.

Any help on this ordeal would be great

All the best!
