$60. plus shipping.The Johnson will dissipate 30 to 35 watts.So I would
imagine $50. and up(Johnson collectors would pay up) for it. Just my

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??
