2465B leaky voltage

 

This morning, I was working with my scope, and I touched the CH1 BNC socket - ground side.
BZZZZ.

I thought I was dreaming.

I measured the voltage to AC Ground - 113VAC!!!

So something's leaking somewhere.

This is a 3 wire AC system - Live, Neutral, Ground.

I immediately checked my Signal Generator, on the same outlet - just fine, so it's definitely the scope.

Before I start poking around, does anyone have some fast pointers, to zero in on?
