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?

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.
