A Low-Mu Triode Preamp - Pete Millett`s DIY Audio pages
... The most visible functions of a preamp are to provide source signal selection (e.g., CD player, phono preamp, and so forth) and volume control for your audio system. A preamp doesn’t really need very much voltage gain; in fact, some designs, called “passive preamps,” don’t have an amplifier stage at ...
