Boatanchor items For Sale:

High Impedance, Vintage Military Headphones:

I have two pairs of vintage military type headphones.
Both are very similar, but not identical.

The DC resistance measures about 1000 ohms, so these are high
impedance headphones. They both have a nice cotton covered cord
that has a "Y" about a foot from the headphones where it separates,
with one set of wires going to each headphone. They have nice
rubber pads on them, which appear to be in extremely good shape.

One pair looks like new. Obviously they are not new, but this pair
looks new. It says "Made by Wm J Murdock, Chelsea, MA" on each ear
piece. The radio end of the cord has small spade lugs. $50

This pair has had some use, but are in very nice condition. They
say "R-14, Made by Utah, Chicago, Signal Corps, US Army" on each
ear piece. The radio end of the cord is terminated in a 1/4 inch
mono plug. $35

Accessory Items for SBE-33 HF Transceiver:

All of these parts work with an SBE-33 HF Transceiver.
They may also work with an SBE-34.

AC Power Cord
This 3 conductor power cord plugs in to the SBE-33.
It includes a relay for activating a linear amplifier
(which uses the same female 11 pin "Octal type" plug), in
addition to the 120 Volt AC cord. The plug includes the
hood. $18

Pair of final amplifier tubes
This is a pair of PL-500/27GB5 tubes. They were "spares"
for the rig. $10

Microphone Adapter Cable
Cable to go from the large 4 pin Amphenol connector on the
SBE-33 to a female 1/4 inch stereo connector, so that a mic
with a more standard 1/4 inch stereo plug can be used. $10

Buy all of the above for $35.

Eico 751 AC power supply / Speaker:

This power supply is used with tube type transceivers.  It
includes a speaker as well as the power supply in a very
nice cabinet.  It was designed to be used with the Eico 753
transceiver, but can be used with most any of the tube type
rigs from the 1960's and 70's.

The manual says it provides the following voltages:
750 V DC at 300 ma High Voltage
280 V DC at 170 ma Low Voltage
-100 V DC at 5 ma for bias
12.6 V AC at 4 amps for filaments

This supply comes from a silent key estate; I am sure it has
not been used for years.  I do not have a rig to test it, but
would expect it to work fine, but the filter capacitors likely
will need to be replaced, as is the case with any of the units
of this vintage.

With manual for $125.

Bird 43 Watt Meter:

The Bird 43 is an insertion type RF watt meter, designed
to measure RF power and load match in 50 ohm coaxial
transmission lines. It is intended for use with CW, AM,
FM, and TV modulation. It measures power from 100 mw
to 10KW, depending on the element used. The meter provides
direct readings in watts with an expanded scale for easy
reading. The scale is graduated for 25, 50, and 100 full
scale. Elements are available in a variety of power, and
frequency ranges.

This particular meter is model 4300.21 manufactured in
March 1957, so it is the older, well constructed model.
It has "N" connectors, with the leather handle, which
is in good shape.

The meter works well. $165.

Low Pass TVI Filters:

A low pass TVI filter is added to the transmitter to reduce
harmonic interference. All have SO-239 connectors and are 50
ohm filters.

Johnson 250-20
This cylindrical low pass filter has a cut off frequency
of 45 MHz and 75 db of attenuation, and is adjustable.
Rated at 1000 Watts AM, or 5000 Watts PEP SSB.
The fact that it is adjustable, means you can get rid of
more TVI, and it is rated to handle higher power than most.
A real win-win situation. $30 or with mounting bracket, $35.

Drake TV-3300-LP
This is a modern low pass filter has been optimized to have
more attenuation in the 40 MHz region, where many TVs have
their IF.  According to the manual it is good for 1000 Watts
"average", which would be about 2000 watts PEP, and has over
80 db attenuation at 41 MHz.  SO-239 connectors on each end.
This one looks close to new, and also has the single page
"manual" with it.  $30

Drake TV-1000-LP
This is the filter that may also be used on the low end of
six meters, as well as HF.  It is good for 1000 W below 30 MHz,
and about 200 W up to 52 MHz.  $30

B & W 425 (same as FL-10/1500)
Cuts off just above 10 meters, and handles 1500 Watts.
Newer case style, $30.
Older, heavier copper style case, painted gray. $35

Para Dynamics PDC 1089
This filter is rated at a full Kilowatt, up to 30 MHz.
5 x 6 x 2 inch black box, instead of the long enclosure.

and could be doubled for 20 meters, tripled for 15
meters, etc.
