**** VHF Amplifier ****

Late '70's vintage likely Military, probably airborne, VHF power
amplifier assembly.  It consists of 7 almost identical amplifier
assemblies
clustered around a central housing that has splitter combiner networks
which are plugged
onto each end with a bunch of SMB connectors.  There are TNC's for the
main in's & outs.   I think it was originally configured as one amp,
driving two, driving four boards. The complete assembly measures 7.5" x
5" x 3.5" overall -- the individual RF amp boards are 4.5" by 2".  The
outer covers are mostly missing. Each  amplifier is a push pull design --
they appear to be 50 ohm in & out impedance with either PT6747 or PT6702
TRW transistors.  I would guess this unit operates on 28VDC.  I don't
know what frequency range it covers nor the power level though, just
guessing, it probably puts out at least 100W.    And there is no
manufacturer name -- probably went with the outer cover.  Six of the
modules are marked OK and one, the input stage I think, is marked NO
Good.  The individual amps have integral heat sink plates so, they could
be removed from the assembly and used separately. Think of it as 7
amplifier boards @ $10 ea -- Bare PCB's would cost as much! -- $70
