Uses CA3094B programmable opamp to drive complementary- symmetry power-output transistors. Intermodulation distortion is only 0.2% when 60-Hz and 2-kHz signals are mixed in 4:1 ratio. Location of tone con| trols in feedback network improves signal-to-noise ratio. Hum and hoise are typically 700μV (83 dB down) at output.
