Abstract :
RIAA equalization with ± 4 db bass control and ± 8 db treble control have been achieved, along with negligible hum, noise and distortion, in a transistorized stereo preamplifier developed for use with magnetic cartridges. Simple circuit modifications adapt this preamplifier for use with most magnetic cartridges.
