Low-cost amplifier provides lowimpedance balanced output from unbalanced signal output of preamp. Response is flat from 10 to 20,000 Hz, and distortion less than 0.1% at 800 Hz into 600-ohm load. Gain is 20 dB. Other opamps, such as LM307 or 747 (dual 741) can also be used.K. D. James, Balanced Output Amplifier, Wireless World, Doc. 1975, p 576.
