Soundblaster Preamp - Fixes that well known problem HOME

The Sound Blaster 16 PCI and Sound Blaster 16 ISA do not have a very sensitive microphone input. This little one transistor amplifier is powered directly from the microphone jack on the sound card and has LOTS of gain. Just put a 100uF bypass capacitor in parallel with the diode to increase gain even more. Note that sound cards other than those mentioned above might not supply the correct power to run this amplifier.
