1940 Lorenz Textophon wire recorder
Hi,
I started to restore this very nice machine. It's basically an improved Poulsen Telegraphone with tube amplifier, remote control and easily changeable wires housed into what is the oldest known precursor of the audio cassette.
It uses German Telefunken EF12 tubes and the like.
I wish not to alter its authentic aspect so I will empty the old capacitors to fit new ones inside.
Any technical information will be welcome.
Thanks,
David
