Need some smart electrical people to chime in...

Good to know, so when Halen posts about repairs to his sexbot, we have someone in house. That is why he sold off all his audio gear for those not in the know.

so, I am too darned lazy to re-read this whole thread, so I am just gonna drop two thoughts here, as-is and FWIW.

1) The leakage to the front panel may be normal and meet UL guidance (or whatever).

2) The current focus on the outlet and/or circuit suggests a simple troubleshooting opportunity -- and I apologize if this has been tried and I just missed it or forgot!

Has the OP taken the tingly component*, disconnected it and then plugged it in on another circuit? Another interesting thing to try. Disconnect only the interconnects that connect the tingler to other hardware, then power it up and test for tingles.

Grounding/ground loops/ground currents are wily things, IMO/IME

___________
* since it's the amp, I realize this is nontrivial. BUT -- It does permit the reductionist approach of unplugging things from the amp piecemeal, then checking for da tinglez. If the amp is isolated completely (i.e., no speakers connected), just turn the volume to zero and turn "off" the speaker outputs (if possible). If not, the amp should be happy with open circuited outputs... or one may install dummy loads if one is extra-concerned about the amp's safety.

... and, again, I apologize if the OP's done all this already!

Only if he could also use your kitchen after said varmint has been apprehended.....

Based on the description it seems to me it's a ground loop in the system caused by the CD player. If it's taken out of the system does the vibration go away in the other components?

The Yamaha integrated is over built to prevent external mechanical vibrations.

Do you mean electrical people like a model XQJ-37 nuclear powered pansexual roto- plooker?

Appreciate the advice. I did do a lot of that and isolated it to the CD player and the amp each able to "tingle" the other via the IC's connecting them. Even if the component "being tingled" is unplugged from a power source. The difference being that the amp needs to be powered on to be the tingler, the CD player will tingle even with power off.

I don't really want to move the amp around but will try the CD player in different outlets to see what happens.

See above post for the answer. Also these are not mechanical vibrations but very low AC current being conducted through my body to ground. The vibration is 60 Hz. For instance if I touch a tingling component and reach across to the metal frame of my fireplace then the fireplace frame feels tingly.

Being the owner of an old commercial building, checking the wiring is a good idea. We redid the whole building about 15 years ago, as the circuit breakers in 3 boxes were unavailable anymore and there were dozens upon dozens of unused wires that were live but not connected to anything on one end. When all the old cloth wires were removed, the area where the boxes are is almost 10 degrees cooler and all the lights are brighter too. And the constant hum heard was dropped about 90%.
