Mezmerize B1 Buffer

The Mezmerize is a direct coupled preamp (no coupling caps) based on Nelson Pass's B1 Buffer. It boasts symmetrical Salas shunt voltage regulators that use LED strings for very accurate voltage reference.  The PCB has provisions for up to 6 relays for input signal switching and an output relay for delayed start-up muting.These boards are intended for adventurous / advanced DIYers willing to dedicate their own time to research what's needed to complete their project.  There is no complete project kit, no parts kits, and no build guide.  It's an amazing project for those looking for something different.   Please visit the Mezmerize Helpdesk Thread for questions.
