Hi there.
I had a question about vac. Everyone keeps asking if my amp is a 240v (I live in Australia). On the back of my amp, where the power cord goes in, it says 120v. But the fuse next to it says 250vac. So is my amp a 120v or 250v? I'm confused.

The fuse won't tell you the voltage of your amp. The fuse is just rated for 250 volts. The amount of current (amps) is what causes a fuse to blow, not the voltage. If your amp uses the standard IEC power cord, I would assume it is 120v. What type of voltage are you plugging it into currently?

If I'm not mistaken ALL of Australia is 220-240VAC and uses a grounded 3-prong plug that is unique to your country. Well, not totally unique. I believe it is the same plug we use here in the USA for 240 volt applications like air-conditioners and electric ranges. So if you are using that type of plug into a normal outlet and your amp is working normally then someone has replaced the power transformer in that amp and didn't bother to placard it indicating the change to 240 volts.
Another issue is the fuse. Whatever the amperage rating is for that amplifier using 120 volts, it would now use a fuse HALF that value running on 240 volts. If it used to take a 2 amp/250 volt fuse it now needs a 1 amp/250 volt one.
I assume you bought this used, right?
I used to work for a company that made equipment that was installed all over the world and I was in charge of making sure that when it shipped it had the correct transformers and such. It sometimes could be quite confusing but I had a booklet I got from the US Dept. of Commerce that had that information.

I believe that there is now a Z dealer in Australia - might be worth a call to them.
