Hello all! Just got mine yesterday and love it, but have an issue that hopefully you can help me with. The magnet lock is not working, and from doing a search it seems it may be a fuse. So I took out the fuse in question, F904. Now, I am an extreme newbie to pinball, and am hoping just switching this fuse will fix it. Now, from what i have read it seams this is a 3A slow blow 250V. Is this hard to find? Will I need to order online or can I use something else? Also, if it is not the fuse, would it be the coil not working? Thanks for all the help!
