New manufactured equipment - Easy to handle - Special devices upon request


Photo RM 1 Vacuum Tube Tester and Vacuum Tube Checker

The RM 1 is a Vacuum Tube Tester easy to handle, in it's construction almost unique, which enables a fast, simple and precise plate current measurement of the most common double triodes (6SL7·GT, ECC81, ECC82, ECC83)¹ and power pentodes (EL34, KT88, 6550, 6L6·GC, 6V6·GT, EL84)¹.
It captivates by a stressed classical outfit, primarily consisting of a solid beech wood cabinet and a surface of anodized aluminium. Because of its small dimensions it is easily transported and it doesn't need a lot of space for accommodation.


Using the RM 1 Tube Checker it is immediately possible to do an exact plate current measurement without doing the often very toilsome procedures mostly necessary with classical devices. Put the electron tube, which should be measured, simply into the accordingly marked test socket, switch the equipment on, select the socket by using the rotary switch (it is indicated by a LED), wait for approx. three minutes till the tube is working stabile and read off the value on the panel meter.


Because all operating voltages produced during the measurement inside the device are stabilized, only selected components are used in the RM 1. The Tube Tester RM 1 delivers precise measuring results, which are mostly not reached by many historical devices.


¹On request it is possible to re-equip the Tube Checker for measuring other vacuum tube types!


For triode fans, for example, it is possible to replace the test socket EL84 by a 300B socket or to change the connection of an ECC82 socket, so that the values for a 12BH7 can be determined. Our price list gives more details and examples for custom-made devices.


The scope of supply includes detailed operating instructions, a conversion table and the nominal values of the tube types which can be measured.
