[Test-Equipment] AC Voltmeters, Variacs, and other items FS

[Ken Simpson, W8EK]

Precision AC Voltmeters, Variacs, and other test items For Sale:


Precision AC Voltmeters:

I have two very precision AC Voltmeters available. Both have
large mirrored scales for extreme accuracy.

Weston Model 443
This is a traditional meter, that looks much like a precision
VOM. It has a leather handle, and has terminals on the side
for 150, 300, and 600 Volts full scale, rated for 25 to 1000
cycles. The scale is a 4.5 inch mirrored scale. It is in
extremely nice condition. $25

Sensitive Instrument Research Model AEW Edgewise Meter
This meter is an edgewise meter made to be mounted in a 5.5 x 3
inch cutout, and extend about 5 inches behind the panel. The
meter has terminals on the back for 7.5 and 150 V AC full scale.
It would seem ideal for measuring filament voltage as well as
line input voltage. It says it has a "Diamond Pivot", and has
a 6 inch long mirrored scale.
Great condition for $30.


Variacs:

Staco Type 033-3587 Variac
This Variac is rated for 10 amps output at up to 140 Volts AC,
50 to 60 Hz.  This one is in very nice condition.  The knob even
shines, and has a nicer pointer than most I have seen.  The
scale is crisp and nice. It will just barely fit in to a medium
Priority Mail Flat Rate Box, so shipping will not be too bad.
$50

General Radio Type M2 Variac
This is an open frame type Variac, made to be mounted on a panel.
It is rated at 2 amps, so this is a smaller one.  It includes the
hardware for mounting to a panel, and a nice 2 inch diameter knob.
$15


M C Jones VHF/UHF Wattmeter:

This MC Jones Wattmeter is a vintage unit, probably from just
after WW II. At that time, it was the gold standard of wattmeters,
basically equivalent to a Bird today.

This particular meter has N connectors in and out. It reads 12
Watts full scale in the forward position, and 4 Watts full scale
in reflected. It also has an SWR calibrate and SWR scale on the
meter. I think the frequency range is from 20 to 1000 MHz, but I
am not 100% positive of that. It works well on 2 meters and 440
MHz. The RF sensor unit inside is model 576.3.

This one functions fine, and looks extremely nice for its age.
$60


Heath HN-31 "Cantenna" RF Dummy Load

This is the traditional Heath dummy load that will handle a
kilowatt. It has a derating curve both printed in the manual
and on the can.

I measured the resistor and it is 47 ohms, so obviously it
is in good shape and a great match for 50 ohms. The cantenna
itself is in really great shape, with no rust, dents or dings.

Paper work is included for $45.


19 inch Relay Rack Shelves:

This black shelf in made to fit a standard 19 inch relay rack.
The shelf itself is 17 5/8 inches wide (standard width for
inside of the rack) by 18 inches. It attaches to the rack so
that 4 inches of it extends in front of the rack and 14 inches
behind the rack (or you could reverse it for 14 inches in front
and 4 behind). It has vent holes so that equipment that is set
on it can get some air. It requires 4 inches of rack space.

It is similar to one seen here
http://www.l-com.com/item.aspx?id=8487
or
http://www.rackmounts.com/Middle-Atlantic-U2MS-DF2984.html
except 4 inches of it extends past the mounting point.

These are in extremely good condition. I can not find a scratch
on them. They look new. Two are available. Buy one for $35,
or both together for $65.


Micronta 21-194 Digital Multimeter:

This DMM not only does the traditional things that DMMs do
(measure voltage, current, etc.), but is also a transistor
tester and a capacitance meter. Voltage ranges are up to
1000 Volts, current to 10 Amps, and capacitance to 20 microfarads.

This particular meter looks good, and functions fine on all
modes except resistance.

Probes included for $15.


120 Volt AC Power cords:

These are power cables that plug in to the 120 V AC line.
They have the standard 3 prong plug on one end, and have the
"International" 3 slot socket on the other end, as is used
on most computers, plus many other pieces of electronic
equipment, such as ham gear and test equipment.

These all function fine, and look very good. Some have been
used, and some may not have been. $1 each.


Prices do not include shipping from Florida.

Thanks.
