Hi, the amp uses slow blow fuses and they do not go with out a reason, you probibly have one or more bad output and driver transistors or the plastic round diode rectifier bridge near the power transformer shorted out(pretty common with a lot of heat.hears what I would try. Get some 1 amp 3ag style fuses and a in line fuse holder from radio shack, replace the bad fuse with it, then unscrew the 2 wires that go from the bridge to each large filter cap, put a dc volt meter across the 2 wires with the meter set to a 100 volt range and turn the amp on. If the fuse holds and you see about 40 volts on the meter than the rectifiers are ok and you need to start pulling the heat sink mounted outputs and check them out for shorts.The only other thing that may have blown the fuse is if you where playing outside on a genorator, as their regulation sucks and they can have large voltage spikes that may have taken out the fuse.Let us know how you make out.When you get it up an running the reverb question is easy.
