Good Morning everyone,
I have written up a few more items from the bottomless estate sale...
I have some kind late '70's vintage likely Military, probably airborne,
VHF power amplifier assembly for sale.
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 amp boards 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
easily
removed from the assembly and used separately.
Asking $70, plus shipping, if necessary, naturally.
*********************************
And I have a pair of heavily built RF Attenuators for sale. They are
adjustable between 0-50dB in 10dB steps. They have 8" flying leads with
one terminated in a BNC Bulkhead female and the other with an N Male
connector. They look like they should be good to at least 1 GHz.
These are 3 1/2" diameter by 4" deep overall and weigh about 4 pounds
each. There are tapped holes in the front frame for panel mounting. No
manufacturer is indicated.
They have 3/8" shafts that adjust by pulling (with a spring return) and
turning so there is no chance of inadvertent resetting. No knob nor dial
is included.
Asking $25 ea plus shipping, if necessary, naturally.
********************************
Finally, there is a 10 Meg meter resistor assembly used to measure 10KV
with a
1mA meter movement.
It consists of 2 large, 10" long, 5 Meg resistors mounted in a nicely
made 12" x7" x 2" plexiglass housing.
Asking $10, plus shipping, if necessary, naturally.
