I turned my amp on today in Variac mode, and before I switched from stand-by to ON, it switched to off/on very quickly about 2 or 3 times, then it simply turned off and I could fell a burning smell coming from the back. I immediately pulled the plug from the outlet. Checked all connections, it would not turn on again. The smell seems to be coming from the transformer located below the footswitch jack. Strangely, after a few minutes, I tried to turn it on again and it did normally, but I did not let it on for more than a few seconds. The fuse is ok, all tubes were replaced recently.
Maybe it is that bad diode problem? Could be the diode smelling like that, or the transformer also could burn like this?
