Leyden Jars to Lodge for the demonstration of electrical resonance

A total of 60 cm high the wooden base plate 32 X12 cm beautifully restored in completely original condition, see also the photo of the early catalogue of Max Kohl in which it was depicted

will be packaged very carefully and sent by registered mail

One jar is fitted with a closing wire containing a spark gap limited by two brass balls, the other contains a fully closed circuit, the length of which can be varied by means of a movable piece of wire. in addition, the inner layer of this last jar is connected to the outer one by means of a closing circuit interrupted only by a very small spark gap. both jars are placed next to each other so that the closing circuits run parallel to each other. the first jar is now energized with the fixed circuit by an inductive apparatus, the second jar is also discharged by resonance with each spark, provided that the sliding contact has the correct Correct position: If the sliding contact is moved a slightly, it will disturb the resonance and cancel out the secondary discharge
