Tube Tester W 19.

This Tube Tester may be connected with any AC line outlet since it can be adjusted to 110, 125, 150, 220, 240 volts. The adjustment is made inside the equipment at the line transformer. After having removed the cover at the bottom, the soldering log is screwed under the corresponding terminal on top of the transformer. The equipment is delivered with the connection made for 220 volts.

The fuse in the fuse holder (see no. 1 of the picture) is for 1 amp. it is available everywhere. For 110, 125, 150 volts line voltage a 1.5 amp. fuse is also permissible. 10 fuse are in compensation to each valve tester.

A high-vacuum full-wave rectivier tube AZ 12 is provided inside as DC supply for plate and screen voltages. Since the equipment is delivered ready for use, this rectifier tube is already contained in the tester.

To assure constant plate and screen grid voltages, a voltage regulator tube GR 150 DA is also contained in the equipment when delivered (Don’t tamper with it!) Since the tolerance of this tube must be very small, it is recommended that spare tubes be obtained only from us.

The plugs (no. 5 of the picture) are kept in special holes at the rear edge of the panel. It is not admissible to put them in the jacks at random because then they may cause a short if the tester is switched on without a test card bling applied.

The tube tester has an input connector which fits a normal appliance connector. The line cord is not supplied together with the equipment. The lid may be removed from the case.
