10 kw / 10 mW Input
More images coming soon!!
(EQP) WEST-FG-10
Westinghouse type FG-10 Audio Amplifier - 10 kw. Accepts 600 ohm input signal, 10 mW maximum and produces 10 kw output at impedances from 1.6 ohms up. Frequency response 30 - 10,000 Hz @ ±1.5%. Total harmonic distortion less than 5%. Reduced output available below 30 Hz and up to 20,000 Hz. Multiple tapped output transformer allows a wide range of output impedances.

Uses a McIntosh K-1071, 200 watt amplifier as a driver, feeding four (4) WL-5736 triodes with plate dissipation of 2500 watts per tube and maximum DC input power of 4200 watts.

Useful for driving vibration testing equipment or other industrial applications. Single channel, not stereo.

Another feature of this unit is that it only requires 23 square feet of floor space in a 82-1/2" tall cabinet. Condition of unit is excellent. Probably never used, but 60 years of dust. Manufactured in 1953. Weighs 2,500 lbs. Manual is included. Sold as-is. No warranty expressed or implied.
