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. Included in the board are provisions for up to 6 relays for input signal switching and an output relay for delayed start-up muting. Being based on the B1 Buffer, Voltage Gain should be close to 1.

"Ten Years After" Special reissue
The new PCB bring some improvements over the original:
The mounting distances are now compatible with the Hifi2000 perforated chassis baseplates that the diyAudio store carries
The five LEDS +/- voltage reference chains in the PSUs now work with equal current bias as in the vintage Hypnotize hot-rod version
