I found an "original" Talking House on ebay. ~$20 + $10 shipping.
I'm beginning to think it was a mistake. When I got it I unboxed it on
the kitchen counter and plugged it in. The ground fault breaker tripped.
I got the DMM and checked from the line to nutral of the plug and got ~120
ohms. I checked line/nutral to the ground pin and it is open.
I took the 4 scews out of the bottom. The bottom comes off and everything
is mounted to the top. It appears to have a shielded
3 wire power cord. Black + White +Green + uninsulated braid.
There is a small power transformer. Black and White are each connected
to one transformer lead. Green and braid are connected to the transformer
frame. There ts a wire from the transformer frame to one of the circuit
boards. There is a wire from nutral to the same board.
I plugged it into a non ground fault outlet and it powers up.
Apparently there is cicuitry to prevent it from working if it is not
plugged into a grounded outlet. I looked around the net and could
not find anything so it's just sitting in a pile for now.
