Refer Silicon Chip April 1994 Based around the low noise LM833 dual op-amp IC, this preamp is designed for use with a magnetic cartridge, cassette deck or dynamic microphone. The performance of this design is far better than most preamps in many stereo amplifiers, making it a worthy replacement if your current preamp falls short of expectation. It features RIAA/IEC equalisation, and is supplied with all components to build either the phono, tape or microphone version. Measuring only 80×78x30mm, it is ideal for incorporating into existing equipment and is hence supplied with PCB and specified components plus PCB standoffs for mounting. +/- 15VDC required. Use Cat KC-5038 and Cat MM-2007 if power is not available in your equipment.
