I have a Fromtman 15G I've been using as a practice amp (and live a couple times) for about a year and never had a problem with it. Last night I was playing on it with my phone plugged into the auxiliary input. I played for a few minutes and heard a kind of popping/scratchy noise, like you'd hear if you moved a bum cable the wrong way. It happened once for about a half second and ten went back to normal. Then give or ten minutes later it made the noise again and the amp *s!!t* down--no noise, LED off, like it was unplugged. I opened it up and checked the fuse and continuity on the switch. Both were good, so now I'm out of ideas.
In typing this out I realized I should check the transformer secondary and make sure the IEC plug is working. Assuming those are okay, where should I look next?
