Lawrence Enteriainment and . Piano Recital Also Will b Be Broadcast, A varied program, featurd outdoor concert of the United Army Band at the Washington racks, will be broadcast tonight by WCAP. The band concert is the open- ing attraction and is scheduled from 6:30 to 8*0'clock. “Bob" Lawrence, who has been ab- sent from the microphone for several months, wil Ireturn tonight and pre- sent one of his fnimitable programs. The names of the artists he has cor- ralled for this program have not been revealed, but it is understood a ma- jority of them are old favorites with ‘AP’s audience. After the Army Band concert, Pen man Thompson, sports editor of The Star, will give his usual resume of the base ball results in the major leagues. Folowing him, Miss Vir- zinia Ludlow, soprano; Miss Lucy Hopkins, contralto, and Conrad Young will give a joint recital. T only other musical attraction is a cital by Wilmer T. Bartholomew, planist. When WCAP signs off at 10:30 o'clock, WRC will take the air and broadcast a special- concert by David Boyd's Willard Hotel Orchestra.

You Should Know About Vacuum Tubes—Part TIL. For purposes of comparison later in this series, I am going to lst in this article the specifications and char- acteristics of the standard tubes which I am discussing. The first in the series is the UV 200 and C 300. These two tubes are identical in characteristics, the dif- ferent code numbers being merely the code- numbers of the two organiza- tions, the Radio Corporation of America and E. T. Cunningham, Inc., which market them. This tube is a gas content tube hav- ing the highest efficlency as a detector under critical adjustment of filament and plate voltage. Maximum eff- clency as a detector can only be ob- tained when a vernier rheostat and patentiometer control of plate voltage is used. Best adjustment of filament current is obtaimed with a vernier rheostat having a maximum resist. ance of 4 ohms, although a 6-ohm rheostat can be used. The negative terminal of the B battery should be connected with the movable arm of a poentiometer of 200 to 400 ohms’ re- sistance. The terminals of the re- sistance element of the potentiometer should be connected across the A battery. The connection is illustrated in_the diagram below. This same connection holds true whether the tube is used as a simple one-tube non-regenerative detector, a regenerative detector or as the detec- tor of a elrcuit using one or more ages of radio frequency before it. Change of Audibility. The value of using o potentiometer adjustment for this tube can be real- ized by plotting curves of the relative audibility under different conditions of plate voltage. Such curves will show that while a relative audibilit- of 70 is obtained at 201 voits the au- dibllity drops sharply to a value of 40 when the voltage is changed to 18 velts. The same thing occurs when the voltage is raised to 22 volts. The change of a half a volt is sufficient to cause a considerable change in au- dibility. P ‘The output impedance of the UV 200 and C 300 tubes with a plate po- tential of 20 volts is 10,000 ohms. The rated filament voltage is 5 velts. ‘What Six-Volt Battery Used. To get fhis required voltage it is necessary to use a 6-volt storage bat- tery with a rheestat having a resist- ance of about 2 to 4 ohms. A stand- ard 6-ohm rheostat can be used. The 1ube should be controlled by an inde- pendent rheostat for best results, Reproduction Prohibited. ‘The filament curremt at the rated voltage is one ampere, giving an en- ergy consumption for the filament cir- cuit of 5 watts. s+he plate voltage required is 18 to 25 volts. At such voltages the B bata tery current consumption varies from . to 1 milliampere. The B battery energy consumption varies then be- tween 0.0045 to 0.625 watts. A grid condenser and grid leak must be used with this tube, The values i of grid condenser capacity and grid leak resistance are not critical. It is general practice to use a grid con- denser of .00025 mfd. capacity and a grid leak of from 2 to 5 megohms’ re- sistance. The lower value of grid leak resistance gives best results on local stations while the higher resistance gives better results on distance re- ception. are: Diameter, 1% inches; 4 5-16 inches. The base is a standard type known as the Navy type base, with grid and ! plate prongs adjacent to each other. Tomorrow I will discuss the char. acteristics of the UV 201, WD 11, WD 12, C 11 and C 12 tubes. OLD PALACE ABLAZE. Fire, However, Is Quelled Without Serious Damage. FONTAINEBLEAU, France, July 15 UP).—Fire broke out yesterday in the Palace of Fontainebleau, which occu- pies the site of the Chateau, founded by Louis VII, who died in 1180. The flames, which were first observed in a loft over the chief architect’s apart- ment, spread rapidly and sent a thrill of anxiety throughout the town.

BANCROFT, ENVOY TO JAPAN, ILL Illness First Thought to Be Slight Indigestion, May Be More Serious. By the Associated Press. TOKIO, July 156.—Edgar A. Ban- croft, American Ambassador to Japan, who is spending the Summer at Ka- ruizawa, central Japan, has been ill for some days. It was at first thought he was suffering from a harmiess at- tack of indigestion, but mow doctors are not certain whether his illness is due to an ulcer of the stomach. The Ambassador is confined to his bed. The physicians are not optimistic, but no serigus outcome is seen at present. Elgar A. Bancroft of Chicago was appointed Ambassador to Japan in August, 1924, and assumed his post in November of that year. He is 68_years old. Karuizawa, where the Ambaasador is spending the Summer, s a popular mountain resort where many of the foreign residents of Japan, including a large number of Americans, have Summer cottages. 2 ( MOTHER;- Flet el K endd. cher’s Castoria is a pleasant, harmless Sub- & stitute for Castor Oil, Paregoric, Teething Drops and 3 enport; rlhgl | General Electric Compan. 21 Plants, About One-Fifth of Total, Consume 1,500 Watts or More, About one-fifth of the Clas casting stations in the United Stytes have availed themselves of the re- cent regulations permjtting increased power. ~Department of Commekos fig- ures made available today show that at present 21 plants are considersd supér-power stations and are using an output of 1,600 watts or more. The real super-power broadcasters now on the ai¢ with 5,000 watts num ber six—KDKA, at Pittsburgh; and WLW W Paul; and WCBD, at Zien City. come two stations with 3,000 watts— WEAF on the Atlantic coast, and KFI on the Pacific. KFI, inciden- tally, is the latest station to jump its power. Atlanta on High Power. Twao stations are emploving 2,500 watts, WTAM, at Cleveland, and WSB, at Atlanta, which, although not yot licensed for 2.300 watts, made ita debut as a super-power plant Monday night under written authority from department. x stations are now using 2,000 watts, namely KGO, at Oakland; WGY, at Schenectady; KOA, at Den- ver: WHZ, at Springfield, and WORD, at Batavia. Tll. Then in the 1,500-watt class are the rematning five “supers’ —KYW HT ‘WBBM, all at Chi- cago; WTAS, at Elgin, I, gnd WQAI, at Houston, Tex. Curiously enough, none of the three Radio Corporation stations for which tha super-power fight was begun at the radio conference last fall _appears’ on the list of those plants which have Jjumped their output. Will Build New Station. under way, however, to v Radio Corporation plant outside the city of New York -with an extensive radio laboratory, for which an experimental license, similar to those now held by the Westinghouse Elegtric Company for KDKA and the for WGY will be asked.
