Mic Preamplifier DIY, this is a current day price of the $5 dollar mic preamp. The mic pre chip is about $5 for a That corp 1510 chip so that still tracks, but the rest of the parts add up in to the $20 dollar range. For a smooth, high gain output, it requires a 1646 Line driver chip, which needs 2 high quality capacitors. The parts count is about 15 items for a bare bones unit.
