Eisen Audio DIY500 Preamp

Projects > Eisen Audio DIY500 Preamp

The DIY500 mkII is a framework kit in 500-series format which allows DIYers to make their own configurations of opamps, transormers, and passive components. Eisen’s website does provide a guide for choosing passive the components, but this kit assumes a fairly extensive knowledge of components and part sourcing. As of June, 2011, the DIY500 is discontinued.
