< > FOR SALE: PHASE LINEAR 4000 preamplifier Originally sold for $600.00 with innovative circuits for noise suppression (autocorrelator) and an expander circuit to restore the lost dynamics due to "gain riding". One channel is intermittent - probably a bad potentiometer(but can't guarantee it). Will sell for $100.00 to a good home.
