Yaesu FRB-757 relay box to switch linear amplifier

Many of the more modern rigs are not capable of switching
the larger currents and higher voltages of the transmit 
receive relays of some linear amplifiers.  This small box
was made by Yaesu to remedy that situation.  Although
it was made for the FT-757, it can be used with almost any
rig that needs a "beefier" relay to switch the linear amp.
It does not even need to be a Yaesu rig.  This box needs
13 V DC (and has an RCA phono plug for that purpose),
and is connected to the rigs linear amplifier relay output 
with another RCA phono plug.  The output of the box has 
both normally open and normally closed contacts, both
terminated in RCA phono jacks.  Contacts are rated at
600 VA AC, 150 W DC load, and will switch up to 250
volts and up to 5 amps.

This unit appears to never have been used.  Paper work
is included for $40 plus shipping from Florida.
