Does anyone on the list have any idea how much an EF Johnson Attenuator box is worth.   This is the device that is placed between the AM transmitter and the liner to drop the RF power from the transmitter to a value that a linear amp can use without overdriving the amp.  Any help with this will be appriciated as I can not seem to find any reference to this unit anywahere. Maybe I am just looking in the wrong place??
