It's the thing on the back of the station that has heatsink fins. With all that said, the CTRL input is basically a variable voltage to the controlled stage. Voltage at this point ranges from about 7 to 14 volts depending on what you have the Power level set to and what the Antenna Network will allow. More volts = more watts, or the other way? Correct.  Transistors like used in this amplifier are current devices.  More voltage (in this case) means more current, which means more output power. I *believe* the controlled stage requires no more than 1 amp of current, and that is why I chose the LM-317T Kevin YAHOO!
