Mezmerize B1 Buffer

  • 2500



Description

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:

  1. The mounting distances are now compatible with the Hifi2000 perforated chassis baseplates that the diyAudio store carries

  2. The five LEDS +/- voltage reference chains in the PSUs now work with equal current bias as in the vintage Hypnotize hot-rod version

Mezmerize B1 Buffer

Grade A engineered board with capacity of upto 6 inputs. PCB mounting for Alps Volume pot, but I would look to mount the board to the rear and use an extension rod to bring the volume control to the front of the cabinet. I have not yet finished building the pre-amp so cannot give anymore comment than can be found on the forums. I think Mr Pass described his original idea for the B1 as an 'electronic passive preamp'
