Complete DUOVAC Tube Tester Kit equipped with the Duokit 4 module, the latest evolution of the Duokit 3, featuring 10 mV resolution for the G1 bias voltage adjustment.

 

The front panel is pre-wired. Only the connectors need to be attached to the measurement board, along with a few power-supply connections, to obtain a high-performance tube tester ready for use.

 

Front panel dimensions: 315 × 209 mm

Duokit 4 Measurement Board Specifications

Module dimensions: 146 mm × 133 mm, maximum height 28 mm, plus backlit LCD display measuring 25 × 70 mm.

Power supply:

  • 110 / 230 VAC mains operation
  • Or 12 V battery operation via an optional DC-AC converter

Power consumption:

  • 25 W typical (35 W maximum) on mains power
  • Approximately 2 A from a 12 V battery

Plate voltage (Anode):

  • Adjustable from 0 to 500 V

Screen voltage (G2):

  • Adjustable from 0 to 350 V

Grid 1 bias voltage (G1):

  • Adjustable from 0 to -100 V
  • 10-turn precision potentiometer
  • 10 mV resolution

Plate current range:

  • 0 to 320 mA with two automatic ranges:
    • 0 to 34.0 mA (0.1 mA resolution)
    • 34 to 320 mA (1 mA resolution)

Short-circuit protection:

  • Full protection

Overall accuracy:

  • ±5% ±1 digit

Note: These are true operating values. The use of a microprocessor enables an ultra-fast measurement mode that minimizes power consumption. Very few conventional tube testers are capable of such measurements, as they normally require large and heavy power supplies. For example, the famous Metrix 310 is limited to only 100 mA of plate current.

Operation

Operation is extremely simple. Using three control potentiometers, the user sets:

  • Anode (plate) voltage
  • Screen voltage (for tetrodes, pentodes, etc.)
  • Grid bias voltage

The corresponding plate current is displayed instantly on the LCD screen.

Measurements are updated at a rate of two readings per second, allowing continuous monitoring of operating parameters and test results.
