High Power Audio Amplifier.-A new variable-frequency audio amplifier (type FG 5/10) capable of delivering either 5 or 10 kw. output power is available from the Westinghouse Electric Corporation.
This power amplifier will take a signal of about 10 milliwatts from any conventional 30 to 10,000 cps. source.and build it up to 5 or 10 kw. with uniform response (~1.5 db).
The type FG audio amplifier is useful in laboratories where a variable frequency power supply is required or in conjunction with high power pulsing equipment, and also in many industrial processes.
