Hey everyone, I have an SWR Workingman's combo that needs some repairs. I figure that this old SS amp is a good thing to learn on. I got this amp for free many years ago and it had a crackly input that would cut out. I left it in a friend's rehearsal studio where I promptly forgot about it. It stayed there for several years before he brought it back to me. Someone had since stolen the fuse cap! So the first part to get this amp working was getting a new fuse cap. I got an OEM replacement off of eBay as well as a set of fuses off of Amazon. I got the correctly spec'd 3A Slo-Blow fuses on Amazon. Well I blew 3 out of 5 fuses before I realized that something is wrong. The amp powers on, and then quickly fizzles out. I haven't gotten it to produce sound because the fuse blows out before the amp fully turns on. The red power indicator light only glows for 2-4 seconds before fizzling out. Did they send me the wrong kind of fuse? Or does this sound like a blown output transistor?
