PREAMPLIFIED DIGITAL LAMP REAMERED - A SCHEDULED SYSTEM
Producer: AVT

The proposed device is a simple stereo tube preamplifier, digitally controlled using a microprocessor. The device resigned from traditional rotary potentiometers and used digital potentiometers, and in addition, tube tuning indicators used as VU-meters were used. Sequential control of switching anode voltage and glow voltage allows to extend the lifetime of the lamps in the preamplifier.

Tile dimensions:

  • power supply 78x108mm
  • 78x45mm driver
