The novelty was created on the basis of the device, which was first introduced in 1946. This Philco dynamic test control device may once again become popular, but now in the form of an iPod speaker amplifier. Although this novelty is based on a device that is already 63 years old, it looks much more stylish than many modern innovations. Under the case there is a 10-watt amplifier on semiconductor elements, as well as a 13.33 cm coaxial loudspeaker. On the side panel are the bass controls, two jacks and the left and right RCA inputs. The iPod dock connects to the sidebar to play music and recharge your iPod. The massive protruding handle at the front is the sound level control.
