Y., W0-2-54391 150 Full details on the "Powerotor" will be supplied by the manufacturer on request. 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 ELECTRONICS WORLD

www.americanradiohistory.com feature high power -to- weight ratio and arc -free operation. They are available with from 6 to 26 volt battery input with output voltages ranging from 150 to 600 volts d.c. Further information on this new line, as well as details on custom units the company is prepared to design, is available from the manufacturer direct. PHILCO TUBE TESTER The Accessory Division of Philco Corporation, Philadelphia, Pa. has just released a new tube tester which has been designated the Model 9200. The new instrument tests cathode emission. checks for shorts and leakage between elements, shorts and leakage in cathodes, and continuity in the heater circuit as well as of internal connection between base pins. Each section of multi -purpose and multiple- section tubes is tested indi- vidually. The roll chart covers all tubes commonly encountered in today's electronic equipment -including 1959 production. Numerous additional seldom - used tubes are covered in a supplement -- including many foreign types now appearing in the U.S. New roll charts will be prepared NEW MANUAL Be preparers to quickly repair all new 1959 sets. radio In this big volume have you easy -to -use, matics, large scheneeded alignment data, printed circuits parts views, lists, voltage information values, on transistors, hints, location of trimmers, and dial stringing, for every almost 1959 radio. auto Includes radios, stereo, portables, and all types and home makes of sets.
