I was listening to my restored EMUD T7 for a short bit this evening and after about a half hour I noticed it was smelling hot around the transformer in the back as I was tuning in a station and immediately shut it down. Pulled the back and the transformer was so hot I could barely touch it and also checked our power coming in and at that moment it was reading 125 volts at the outlet! Icon_eek  That might not have been the peak as while I was watching it was SLOWLY setting back down and finally settled at 122 volts before I disconnected the meter. It's a 117 volt rated transformer, so I am hoping I caught it in time before one of AEP's famous power spikes through here killed it. I've had similar crap happen even out in the buildings, which are a separate line from the house and it drives me nuts! Ancient, outdated lines that are patched on top of patches out here. Icon_evil
No matter where you go, there you are.
