YES you do have something faulty & DANGEROUS. READ ON: There is a capacitor & resistor connecting one side of the power cord & power transformer primary winding to the chassis & thus circut Common. This is known as a Death tap situation today because as you discovered if the cord is inserted wrong way then full wall-outlet AC voltage & current are present on the chassis & all metal jacks or controls. UNPLUG the tuner. REMOVE both of those parts. DO NOT use or plug in the tuner until you do remove those parts. While the 312 schematic wiring diagram is not displayed @ the hhscott web page, the 310 & 314 are and should be adequate to locate those parts. There is also a capacitor ACROSS the power transformer primary winding; this is NOT the offending part, the purpose of this capacitor is to mute turn-off pop sound heard thru speaker. It would be a good idea to replace this switch-muting cap after all these years with a new one.
