I did a bad thing.
Changing tubes on my Lonestar Classic, and I very stupidly had an el34 in the rectifier socket and the rectifier tube in the power socket. It was in Diode mode on Tweed. I was playing around with cabinets and twitched it to full power (I turned it off to switch) and when I turned it back on I saw small bit of smoke. It was on for 10 seconds in full power mode, then immediately unplugged. I pulled the chassis and didn’t see anything,,but there could be something hiding that can’t be seen. I turned it back on briefly, it’s sounds amazing, as always, but got in touch with Mesa tech support to send it in.
