I picked up a Concert Lead the other day and when I plugged it in, I heard a pop and a small stream of smoke appeared out the back. I pulled off the cover and found the end of the problem. Now, I'm not an Engineer, so please bare with me. I'm assuming it was a cap that smoked. It's a cap with 3 legs. there are 2 next to each other and it's the one closest to the back of the Head. I say I found the end of the problem, because I don't think it started there. I've got it at a local repair shop here in Charlotte, but the repair guy said he wasn't sure if he could even find that part. It's day 2 and I haven't heard from him yet. Hopefully, no news is good news and he's able to fix it. But could have this been my fault? I had nothing attached to the Head. Just plugged it in and turned it on. Since this unit has a 1974 Date inside, I wasn't sure if I need to make sure the Head is attached to any form of Speaker Cab. before I turn on the juice. Any thoughts from anyone?
Thankx,
Bob
