DUMMY LOAD
Barker cti Williamson, Inc., Bristol,
Penna, has announced the availability
of a versatile dummy load device which
has been especially designed for off -air
transmitter tests by labs, in the ham
shack, or service shops.
The unit, tradenamed the "Match-
master," consists of a dummy load with
direct- reading ri. wattmeter and standing-
wave -ratio bridge. It is suitable for
applications where adjustment of radio
transmitter power output must be
checked before going on the air as well
as other uses.
The device is housed in a gray -
finished cabinet measuring 6" x 8" x 8 ".
DIAGRAMS FOR OLD SETS
Supreme Publications, 1760 Balsam
Road. Highland Park, Ill. has announced
that it is now able to supply
diagrams and service data on radio receivers
going as far back as 1927.
This information is currently available
in two forms -as bound copies
covering specific years or as individual
schematics at 40 cents each. The years
covered are 1926 through 1948 with
newer set schematics also available if
required.
A 48 -page "Master Index" which
lists all available radio and TV material
can be obtained from the publisher
for 25 cents.
NEW HEATH SCOPE
Heath Company, Benton
Harbor,
Michigan has added the Model OR -1
five -inch d.c. oscilloscope to its line of
assemble -it- yourself test instruments.
The circuit features identical d.c:
coupled vertical and horizontal ampli-
fiers. a 5ADP2 flat -face cathode -ray
tube, and edge -lighted graticule. The
transformer -operated power supply
employs silicon diodes in full -wave
voltage doubler circuits for "B +" and
bias supplies. Critical voltages are
regulated by gas -filled VR tubes. Both
vertical and horizontal channels feature
d.c. to 200,000 cps bandwidth (1
db point) and a sensitivity of .1 volt
peak -to- peak /cm. (uncalibrated).
The scope is suitable for use as a
read -out indicator in computer applications,
in industrial testing, audio development
work, and general utility
usage. Normal frequency coverage is
from 5 to 50,000 cps in four overlapping
ranges.
TRANSISTOR TRANSFORMERS
Microtrrait Company, Inc., 145 E.
Mineola Ave., Valley Stream, N. Y. has
added five new microminiature transistor
transformers to its catalogue line.
The new units are available in open
frame construction with standard channel
or plug -in tab mounting channel.
The transformers measure less than 'z
cubic inch and weigh approximately
4At1ths of an ounce. Impedance ranges
are designed to meet the requirements
of many new transistors.
A 24 -page catalogue carrying specifications
on these new transformers is
available on request.
MICROMINIATURE RELAY
Kurman Electric Company, 191 Newel
Street, Brooklyn 22, New York has
recently introduced a new microminiature
relay as its Model KX.
The new unit measures .4" wide x .8"
long x .875" high. Operating tempera-
ture range is from -65 degrees C to
+125 degrees C. Sensitivity is 200 -250
milliwatts. The new model is offered in
three different header combinations.
The relay will withstand shock tests of
50 G's; vibration frequency of 20 to
2000 cps at 20 G's. Coil resistance is up
to 10,000 ohms maximum and contact
resistance is .020 ohm maximum.
Detailed information and prices will
be supplied by the manufacturer on
request.
TRANSISTOR CONVERTERS
Freed Transformer Company, Inc.,
1773 Weirfield St., Brooklyn 27, N. Y.
is now offering a complete line of static
d.c.- to -d.c. transistor converters as
stock items.
The new units are designed and constructed
for quiet, maintenance -free
operation and long -life service. They
