That sounds like a very risky place to play in if the fuse blowing was indeed caused by a surge of that magnitude. You need POWER CONDITIONING and VOLTAGE REGULATION in that case, not just 'surge protection'.
A 'surge protector' will just blow instead of the amp and will eventually fail. Plus, depending on the surge, it can still get to your amp regardless of how fast the surge protection is.
Power conditioning/voltage regulation will take whatever is coming from the wall and put out clean 120V.
I would strongly advise getting an electrician to measure the voltage coming out of the walls in that place first.
