Power Transformer for TenTec Hercules 444 HF linear amplifier

This power transformer is used with the older Hercules 444 HF
linear amplifier (not the newer Hercules II).  It includes the
molex plug, so that it will simply plug into the 444.  This is
  a "spare" transformer that was never used.

The Hercules 444 provided 48 to 50 volts DC at up to 25 amps
to produce about 1000 to 1200 watts DC input in order to get
600 watts of RF out.  This transformer is roughly a 7 inch cube,
so is a very healthy transformer of approximately 1250 VA, if
someone wants to use it for another project.  $75


TenTec Switching Power Supply:

"Switcher / 25" 25 amp switching power supply:
This is a 25 amp switching power supply in a case that
matches the early Omni series case, with the metal bezel
around it. It is in a case that is the same size as a 243
remote VFO. It has an ammeter on the front, along with
Switch, TenTec logo, and output bulb. The front panel
basically looks like a 280 power supply with a metal bezel,
but says "Switcher/25" on it. It is very quiet, and well
shielded, and does not produce any electrical noise that
I could find. $140


TenTec 234 RF Speech Processor
The 234 is the predecessor to the 715 speech processor
except it matches the early Omni Series A, B, and C rigs,
and others of that era.  It has both a 4 pin plug and a
1/4 inch stereo jack for input.  It needs 13 V DC at low
current.  It is an extremely effective unit, typically
providing about a 6 db increase in talk power.
With paperwork for $150.


Coaxial Antenna Switches:

All work fine, look fine, and use SO-239 connectors.


Waters (B & W) Model 376 Protax Coax Switch:

This five position switch permits all five antennas to be shorted
to ground. It does not short the input connector to ground. This
is the Waters "Protax" series, which grounds all unused antennas
(or all antennas if in the "ground" position.

It accepts PL-259 connectors, with the coax going out like the
spokes of a wheel. There is also a mounting bracket if one would
want to wall mount it.

This one works fine and looks extremely nice.
Paperwork is included for $40.


Two position "Strip Line" Coax Switch:
The MFJ 1702 C switch utilizes metal cavity construction for max
efficiency and high isolation. This two position coax switch has
a new center ground protection! Better than 60 dB isolation at
300 MHz and better than 50 dB at 450MHz. 50 Ohm. The unused
terminal is automatically grounded for static and RF protection.
It has less than 0.2 dB insertion loss and SWR below 1.2:1.
Heavy cavity type construction and SO-239 connectors.
Mounting holes. It looks very close to new.
With paper work for $25.
