My New Neuberger RP270 Tube Tester From Germany

Got me a new tube tester made by Neuberger. The device is made in Germany in 1956.


The device can be configured by hole cards thad are made vor specific tube types. The holes in the cards shows positions vor the configuration pins thad route the appropriate voltages to the dedicated tube pins vor the chosen test on the switch.  With the buttons on the left side of the configuration panel, the connection to the tube pins can be interrupted. This helps to find witch component is shorted in the tube. The device can perform a filament test, cathode, grid 1 to 4 and anode shortage test and also a emission measurement test.
