Description: Four years ago I purchased two DouVac pulse tube testers completely assembled in travel cases along with jumper wires and power cable. This machine was never used and I just turned it on for a picture for this add. I am no longer selling vacuum tubes so do am selling many tube testers now. This tester will have a set of instructions and operation instructions included inside each machine. I took the front plate off and looked inside and see that the heater switch is connected to a transformer for power. This tube tester was designed in France but produced in China. Specifications: Dimensions : 146 x 133 x 28 mm ( h. maxi ) Measurement Mode: Pulsed, run by a 8 bits micro-computer clocked at 12 MHz ADC sampling: 10 bit monotonous (1024 points) Duration of the measurement window: 800 μS Interval between measurements: 0.5 second General accuracy: better than 5% Grid 1 voltage range: 0 to - 100 volts Grid 2 voltage range: 15 to 350 volts Plate voltage range: 2 to 500V volts Plate current ( maximum ) : 340 mA Display resolution, grid 1 voltage: 0.1 volts + / - 1 digit Display resolution, grid 2 voltage: 1 V + / - 1 digit Display resolution, plate voltage: 1 V + / - 1 digit Display resolution, plate current: 0.1 mA + / - 1 digit up to 34 mA 1 mA + / - 1 digit I > 34 mA Supply voltage ( nominal ): 110 V - 230 V 50/60 Hz Tube Protection: By automatic cut-off between measurements ( Vgrid down to - 100 V ) Tube connections: Short-circuit protected.
