Stray current through my audio rack???


I don't know if I am imagining this, but each time I happened to touch my arm or put my finger into the grooves of the theaded metal rods of my Michael Green Audio rack, it feels "live", I kinda get a tingling....is there a way to check if there is some AC going through it?

attach a basic #18awg stranded grounding wire, connecting the rack to a nearby AC outlet ground. Attach the grounding end of the wire to outlet cover-mounting center screw. Use a hose clamp to secure the other bared end to your rack post. This should cure your tickles of any leaking stray voltage from a component. But if it does then you should attempt to invert the AC input plug polarity of the offending device, then test again. Stray AC leakage can result in serious repurcussions to your safety so do be careful.
If you have no meter, unplug everything on the rack or flip your breaker. See if the tingling stops.
