Simple High Quality Preamp For Hi-Fi

For those who are still with me, the preamp featured has optional tone and balance controls which may be omitted if desired (although I do not recommend this generally). The input switching may be extended if needed to accommodate more signal sources, however in this version, no RIAA (phono) input is provided - see the separate Project Page article for a stand-alone phono preamp which can be added if desired. The tone controls do not use the traditional `Baxandall` feedback design, but are basic passive controls, which offer a modest 6dB of boost and cut at maximum. This may not sound like much (most tone controls offer 12 to 20dB), but in reality is usually quite sufficient for such minor corrections as are usually needed. (Note that these tone controls can also be used in the Project 88 preamp).
