FAQ:

Q: What kind of power does a buffer preamp use?

A: The potentiometers are linear taper at 25 Kohm, but again you can easily use higher or lower values as you like. The buffer uses an external power supply from 18 to 24 Volts DC. You can power it with batteries, but most convenient is an external regulated supply running off the wall.

Q: What should voltage gain be on B1 buffer?

A: Being based on the B1 Buffer, Voltage Gain should be close to 1. Please visit the Mezmerize Helpdesk Thread to ask any questions. My build was balanced using two boards, 2 pole selector, and I used two dual pots for separate volume controls.

Q: Can a CD player use a buffer preamp?

A: Obviously, a CD player with a nominal 2V line signal presents no problems at all for the buffer preamp. Most power amps feature an input sensitivity between 1 and 2 V, which mean that a typical CD player needs no additional gain in order to redline most power amps.

Q: What kind of buffer does first Watt use?

A: First Watt’s latest DIY offering, the B1 buffer stage, is described by Nelson Pass as “a no-feedback JFET buffer that offers ultra low distortion and noise with ultra wide bandwidth.”.
