Mars Buffer

The need for a buffer to add a tube to your signal path, without adding gain is now bigger than ever. With DAC’s (Digital Analogue Converters) being so popular, a common problem occurs. The DAC output is too high, and your amplifier plays music at maximum as soon as you turn the volume to 1. To the rescue comes the attenuator with a tube buffer. No matter what attenuation you select, the signal is not degraded and the magic sound of the vacuum tube makes your music sound the way it should.

The design is a cathode follower with a current source

Features:

  • 47k input impedance (22k optional; request on order)
  • 230V mains voltage
  • earth lift option for earthed hifi systems
  • all tube signal path
  • very low noise floor; power supply nulling is achieved by using symmetrical positive and negative rail voltages.
  • hand wired point to point; no printed circuit boards
  • cathode follower circuit using two triodes per channel
  • 6SN7 or ECC88/6N1P/6922 tubes used (specify when you order)
  • AC filament supply for dynamic sound
  • only one polypropylene capacitor used per channel. (zero capacitors are also an option, but DC fluctuations might upset your power amplifier)
  • metal film 6 step attenuator to select volume
  • perfect for modern DAC and CD player output
  • integrates perfectly with Mars stereo amplifiers
