Hi. I'm using my SWR SM-900 amps and GK 410RBH 8ohm cabinet. And from South Korea. When I get the amp, there are only 1 speaker fuse 3AG, 10 amp, fast-blo. I need one more speaker fuse and fuse cap. In my country, no official center of SWR, and the fuse standards is different. So, ?How can I get the fuse, and the fuse cap Thanks.
