ac adapter

I have an electric dog fence. We had an electrical storm the other
night, and the next day the dog fence was not working. After some
trouble shooting, I determined the problem was fortunately not the
transmitter, but the AC adapter. My wife was going out and I sent her
to Radio Shack with the broken AC adapter and with the mission to look
for a replacement. The old adapter has an output on 12 Volts AC and
200 mA. I told her to look for an exact match, but since I knew that
wasn't likely I told her something will less Voltage or Amperage might
work. Well the fellow at Radio Shack told her I was wrong, and that
less amperage was bad and could damage the transmitter, but more
amperage would be fine. He convinced her to buy an adapter with a 800
mA output. So she brought it home and after being plugged for a
matter of seconds, the transmitter was fried.
I call Radio Shack and the guy insists that the 800 mA should not have
been a problem and it was something else that caused a problem.
Is he right? That doesn't make sense to me. To me more amperage
would a bad thing. But I am not an electrical engineer. So if anyone
could help me out here and tell me who is right, I would appreciate
it.
Thanks
