I wanted to ask anyone familiar with the Acoustat TNT 120 amplifier a question about the two fuses that are mounted as you look at the inside of the amp from front to back, these two fuses are mounted about 1/3 of the way from the left side (not on the circuit board near the output devices) of the amp about 1/2 inch from each other one fuse is above the other fuse. The fuse holder wiring on one end goes to the power cord and the other fuse holder wiring goes to the big yellow transformers in the front middle of the amp. The right channel went out this evening so I checked the fuses and was surprised to see 32 volt 5 amp slow blo fuses in the place I mentioned. Is this the right value fuse? I have never seen a 32 volt fuse before. One of the 32 volt fuses seems a little discolored. Unfortunately I don't have a volt meter so I can't check them. I wanted to ask what value fuse could I substitute that would be safe without doing any further harm to the amp? The 250 volt 5 amp slow blo fuses on the circuit board seem fine with no signs of being blown. Any help on this would be greatly appreciated.

This may REALLY be critical. I had Acoustats and one of them caught fire from within that black box. The speaker was a couple of months old - original fuses. I was lucky I was home and was able to deal with it. Be careful.
A fuse is a device that fails when too much current is drawn through it. The amperage value of the fuse is critical. The voltage on the fuse is the arc value of the fuse so that voltage doesn't "jump the gap". In your case, use a fuse of at lease the same voltage or higher, but make sure the amperage is the same.

A 32v 5 amp fuse, that is why the manufacturer put it in. If there is doubt, check the schematic, perhaps it's in the manual/service docs for the amp. An inexpensive DMM would be a good investment along with some basic knowledge on how to use it.
