Waters Universal Hybrid Coupler II -- Model 3002 w/compressor. A fancy phone patch styled to match the Collins S-line. This one is like new in the original box w/ original manual. There are just a couple of hairline scratches on the sides, the front is unblemished. The 1968 price was $72.50, now asking $100 in highly depreciated money! :-)

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! -- $75
