The reconstruction of this rare and relatively sophisticated gramophone took place gradually and with a great deal of patience and respect for the history of these instruments. The entire record player was completely disassembled literally down to the screw and, if necessary, replaced by "an old screw with a new screw". We feel a bit of humility towards the engineers here, because this device has nothing to do with electricity.
We think that if someone embarks on a reconstruction of a similar scale, we are able to advise and recommend what and how we did. Look at the detailed photos of the work and judge for yourself.
