Description
Important and fascinating German medical electrical device “Original Geissler Elektro-Oszillator”, model Type A, number 203, powered by 125 Volts, dating roughly to the late 1920s / early 1930s.
The device was intended for high-frequency electrotherapy treatments and is still presented inside its large original transport case, complete with numerous applicators, electrodes and accessories.
The generator is housed in an elegant wooden cabinet with dovetail joints and a dark top panel, on which there is an analog milliampere gauge, a control lamp, a switch, a frequency regulator (Frequenzregulator), an intensity regulator (Stärkeregulator) and the triangular mark:

Particularly interesting is the set of various interchangeable electrodes/applicators, some in glass and metal, stored in the dedicated compartments of the case. There is also the large wooden cylindrical applicator with original German indications, including “Tiefenwirkung” (deep action) and “Oberflächen” (surface), along with handles, adapters and vintage cords.
On the case is affixed the metal tag:
