Sound Blaster Microphone PreAmplifier: (electronic circuit added 8/02)

Sound Blaster Preamp: Fixes that Well Known Problem and Needs No Batteries : 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. (added 2/05)
