Alec, I get what you're saying but no way or form should power AC appear on the tonearm. I'd suggest also, unplugging and getting under the table specifically looking for anywhere that an unprotected connection or damaged wire in the power circuit might contact the metal top.
Might revise that to include first disconnecting from the amp. But you really need a way to test what's present (voltmeter) I'm not keen on checking by touching if it's already buzzed you.
I'm going to assume when you say "tingle" that you're not talking static -- in other words it persists as long as you're in contact. I'm sometimes zapped by contact with my arms, but I'm (un)fortunate enough to live somewhere that sports relative humidity as low as 4%. Makes a hell of a crackle when it happens, though.
