Default Carrier Current AM Radio transmission

I just got done building a tube am radio transmitter with two 6L11's and I have been doing some reading on Carrier Current circuits. From what I understand the RF signal gets injected onto the power cable, and then as long as you are close to the outlet or wire in the wall your radio can pick it up. However I can not find schematics anywhere as to how to build such a circuit, and I am afraid to just try anything, for fear that I will burn out my transmitter. Please Help!!!!

thanks,
Adam

Here's a National Semiconductor app note for a low power FM one, but I expect similar principle would apply.

I've often thought about building this one. The problem was the line isolation transformer. Anyone have ideas on something readily available that would work?
