The old fuse puffed and your gear's flat. Before you assume the board's toast, check the rating on the blown one — if it says F3.15A, this is your direct swap. This 3.15A M205 quick-blow cartridge fuse (250VAC) opens the circuit fast enough to stop a short from cooking downstream components. It's the M205 format you'll see in all sorts of appliances and test equipment, so if your spec sheet calls for 3.15A fast-blew at 250VAC, grab this one and you're back up
