Delivers 10 watts continuously (20 watts peak) from DC to 1 MHz, and 20 watts continuously at dc, with extremely low harmonic distortion and flat frequency response.
Front panel controls permit operation in any of three modes: fixed gain of 10 (20dB) without phase reversal, fixed gain of unity with phase reversal, or adjustable gain (0 to 10) without phase reversal.
Input and output, independently, may be either direct coupled, or capacitor coupled with input cutoff at 1 Hz and output cutoff at 30 Hz with a 600-ohm resistive load.
