Where is the AC fuse located on the SLI-80

I own a Cary Amp SLI-80 and all of a sudden it does not turn on at all. According to the manual there is an AC fuse inside, but after removing the bottom plate, I cannot find any fuses at all. Wiring goes from the power transformer thru a couple of diodes directly into the pins of the rectifier tube. What's going on?
In amps with one fuse it should be located close to the incoming power and before the power transformer. So look for the IEC, follow the wires...

The pdf manual I found didn't say anything about removing a bottom cover. Sometimes the fuse is incorporated into the IEC. Look real close at the IEC (from the outside) there's a version with a tiny slot, small flat blade screwdriver just fits, pull it out.

Its one or the other. Should be able to find it. It is a tube amp, after all.
Look for a pop out panel on the IEC connector (they are usually located on the back/outside).

Oh my.... good call. I would have never found it. At my age I needed a magnifying glass to see the darn thing.  THANK YOU very much.

If I may ask another question: Is it a good move to get a UPS to "protect" the amp from spikes and brown-outs? We live in Florida with lots and lots of lightning activity.

millercarbon is correct. A lightning bolt with the power to jump 10,000 feet from a cloud to the ground is not going to be impressed with your UPS/surge protector. Unplug your gear and anything electrically connected to it when you hear thunder.
I didn't mean to imply that a surge protector might not be useful, it might protect your equipment when the power comes back on after a power outage. 
sfar & millercarbon: you-all made me laugh. You are right about the lightning; I was thinking more about spikes and brown-outs, which are quite common in our part of FL.  Notwithstanding, I will take your advise and "unplug" when necessary. Thanks again for your help.
What occured to me - and correct me if my logical reasoning is off - is that if I buy an UPS which comes with a strip which has battery backup and another strip which only has spike protection, I can connect my amp to the "spike protection" side and my other components on the battery backup side. I think that might work.
A lot of battery backups have some outlets that are for battery backup, and a few that are not. The ones that do not are only for surge protection. So really you can get all you want in only one box.
