I'm very new to amp repair so bear with me. I purchased a non-working Fender Champion 100, it would not power on at all. I found it had a blown fuse on the pre-amp board, so I soldered in a new fuse, it blew immediately when I plugged it in and powered it. I then saw it had a visibly burned out bridge rectifier and two surface mount capacitors. I replaced the rectifier and capacitors. It at least doesn't blow the fuse when I turn it on now, but all I get is a blinking power light, nothing else seems to power on. Any thoughts?
