MY SET WON'T WORK!

EVERYBODY ELSE TO BLAME!

Tt isn’t so bad when the listener resides in the city, where service is readily available, but the distant npcountry novice listener is np against a serious proposition when he finds his set won’t work. It went very well last night, but to-night it refused to perform. He, not infrequently, writes or wires .to the nearest radio dealer: ‘My set won’t work." The dealer hasn’t much to go upon to diagnose the trouble in his correspondent’s set, but the latter, by some obscure process of reasoning, decides that the dealer will know immediately where the trouble lies. Therefore, he says: "My set won’t work." | Maybe the set, say, a five-year-oid neutrodyne, has only one jack. And. therefore, it is not possible to narrow down the circuit by simple methods to ascertain whether the trouble is in, sav, the detector circuit or the audio stages . Causes of Trouble. Among various causes of the ‘won’t werk" malady. are the following :- (1) A burnt-out transformer. (2) A loose connection in the circuit (3) A valve-prong not contacting properly in the socket. (4) A fault developed in the valve. itself, which may light, as usual. but not function (5) A faultv jack. the phone plug not contacting pronerly. (6) A viece of fluff or dirt caught inside the jack, preventing proper contact. (7) Batteries connected the wrong way. (8) Corrosion on battery connections which can be cleaned off with household ammonia. (9) Batteries run down. (10) A fanit in one of the rheostats Possibly a broken resistance wire These are not all the ills that a radio set may be heir to, but thev are among the most commoit.
