Variable Dc Supply Employing Thyratron Rectifiers

C. power supply shown in the schematic diagram finds its main application in amateur phone and CW transmitters and in laboratories where a variable source of D. C. voltage is frequently desired. This circuit does not require the usual primary variac or a voltage dropping resistor to obtain control of the output voltage. In amateur transmitters the variable voltage feature is advantageous for tuning up operations, where a low plate potential will aid in preventing damage to...

Alignment Of Receivers

Modern radio receivers employ from two up to eight, ten or even more circuits to achieve the selectivity desired. These circuits, however, are of little benefit unless all of them are working at their proper frequencies simultaneously. Only someone acquainted with the alignment of receivers in a radio production department, or someone engaged in radio service work who has adjusted a receiver on which someone has tightened all of the adjusting screws, can realize how dead a receiver can sound...
