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)
