Got a slight problem with my amp in which its broken. I lent it out for a month to a guy that I am no longer on speaking terms with. Unfortunatley it came back not working. I opened it up and found 2 2.5A fuses burnt out so I replace dthem with 3.1A as I though the 2.5A sounded a little low. Unfortunatley the Amp made an attractive fart sound then cut out again. The fuses look fine but I replaced them with 2 new 2.5A's just in case and now the think wont work at all. I dont know where else in the circuit it would have blown. Has anybody got any suggestions?
