Tube Tester / Tube Checker

RM 1 - Beck Elektroakustik (Beck)

The RM 1 is a Vacuum Tube Tester easy to handle, in its construction almost unique, which enables a fast, simple and precise plate current measurement (emission test) of the most common double triodes (6SL7-GT, 12AT7=ECC81, 12AU7=ECC82, 12AX7=ECC83)¹ and power pentodes (6CA7=EL34, KT66, KT88, 6550, 6L6-GC, 5881, 6V6-GT, 6BQ5=EL84)¹. The device has a distinct classic design, primarily consisting of a solid beech wood cabinet and a front panel of anodized aluminium. Because of its small dimensions it is easily transported and it doesn't need a lot of space for accommodation.
