[Amps] Misc Radio Stuff

[Radio WC6W]

***  MISCELLANEOUS ***

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 $150 in highly depreciated money!  :-)

4" Silicon etched wafers, low yield rejects or they wouldn't be here but,
pretty -- $10 ea.

$10 ea.  3 for $25
 
NOS coily cable for a Yaesu MH-27 mike (may fit others).  Later version
with the RJ connector at the radio end.  $10.
 
Motorola Mobile Mike Cable part number 0180700T14, 4-wire coily cord mike
cable with a Motorola 4-pin Microphone connector (similar to Amphenol
MC4M) on one end and a spring strain relief on the other.  There are some
flat pins on the free wire ends -- New in Motorola plastic bag.  $10.
 
NOS fan that fits some Japanese radio...marked:  57 10.01  100V
  The wires from the motor are about 4' long and are terminated in a 2
pin JST connector.  The impeller has 8 blades and is 7 cm in diameter.
  It is mounted to a U shaped metal frame with four mounting holes spaced
5cm by 9cm $10
 
Amphenol MS connectors -- 3 pairs MS20-1 14 pin military style connectors
3 male panel connectors + 3 female cable connectors with shells (two
straight, one 90 degree); some new, some used but clean.  $10 all

Amp 24 Pin plastic circular connectors #16 size contacts, 2 cable plugs
p/n 208837-1, 2 chassis sockets p/n 206838-2, 4 clamps 206138-1, plus
crimp on contacts for all.  NOS. $15
 
Large (uncased) display unit.  256, T-1 3/4, red LED's arranged in a 16 x
16 pattern that is about 5" square.  There is a 6" x 6" mother board plus
16 daughter boards holding the LED's.   The LED's are driven by latches
so any/all of them can be lit.  There is a 14 pin DIP interface connector
-- pin out provided.   $65. 
 
Carter Radio 500K ohm rheostat with 2" diameter skirted knob, calibrated
0-100 over 270 degrees -- $4

Four 37.5K 78W power resistors, used w/mounting clips -- $8
 
Two 200W (or so -- 10" long) 1.5K ohm 10 tap (every 150 ohms) power
resistors, used.  $10 pair
 
Dale 1.5K, 225 Watt power resistors, used.  3 pieces -- $10all
 
Ohmite 2K, 225 Watt power resistors used w/mounting clips -- $4 ea (10
available)
 
Ohmite 3K, 225 Watt power resistors used w/mounting clips -- $4 ea (8
available)

**** 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   

All of the above plus shipping, if necessary, naturally.
