Who can fix electrocompaniet amps

I have an Electrocompaniet 120 that keeps blowing its fuse before it starts up. It worked for 2 months - the distributor took it in twice and kept it for over one year combined in both efforts and it still is not right - the dealer Audio Heaven has been no help and pretty much said it is my problem. Someone mentioned at one point a guy in Florida but I cannot find the thread. It sounded really good for the two months. Would using a different fuse like a slow blow help or different amp - it uses fast blow 5A 250 volt.
