The Application of Rectifier Power Supply to Sound Reproducing Equipment

The application of rectifier power supply units for furnishing the low voltage requirements of sound reproducing equipment demands careful consideration of the filter circuit characteristics as well as those of the sound reproducing equipment. — Permissible ripple voltages are discussed in reference to the sound reproducing equipment in its present form. consideration is also given to the possibility of future improvements of the sound equipment that might increase the effect on the system of the a-c. component from the rectifier filter sufficiently to interfere with sound reproduction. the factors governing load regulation of rectifiers and filters are treated with respect to allowable voltage variation under all operating conditions. — Output voltage characteristics are influenced by such variables as ambient and operating temperatures, manufacturing tolerances, and line resistance variations of each particular installation. this output voltage must be maintained within the range of the current regulating devices in the sound reproducing equipment. description is given of a rectifier power supply unit, covering the electrical and mechanical design, shielding and installation problems.
