Permanent Magnet Dynamic Loudspeaker
Title
Permanent Magnet Dynamic Loudspeaker
Description
According to the website radiomuseum.org the main component of this radio is a Super-heterodyne:
a "radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency."
a "radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency."

Format
Electrics:
The power works through an alternating current supply of 120 volt/capacity. This means that the electric current is continuously and rhythmically reversing directions.
The speaker, made in Taiwan is a Permanent Magnet Dynamic loudspeaker, which uses a moving coil to convert electrical energy into acoustic energy.
