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 80x78x30mm, 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.
