6-tube Ducretet radio
6-tube radio divided in 2 blocks and signed ATELIER DUCRETET E ROGER PARIS.
One of the very first radios made in 1921, divided in 2 blocks, the first one being used as high frequency amplifier and detector, the second one used as low frequency amplifier.
The last photo shows the radio as it was found and as it was used in 1924 (the original TM tubes were replaced by RADIO MICRO tubes which used 8 times less energy and that could last 10 times longer).
