DIORA AGA RSZ-50 ca.1947 from Poland Antique radios are radio receiving sets that are collectible because of their age and uniqueness. Although collectors may differ on the cutoff dates, most would use 50 years old, or the pre-World War II Era, for vacuum tube sets and the first five years of transistor sets.

Bakelite The availability of Bakelite allowed designers to create much smaller and less expensive units, allowing radio to be installed in the kitchen and the bedroom. Bakelight radios were much safer to have in the home than wooden radio consoles, since they did not burn in fires but just melted. However, Bakelight radios had problems with melting from the heat of the vacuum tubes, they also had problems with stress of holding themselves up, causing thin hair-line cracks in the plastic. When these radios were dropped they would smash apart, unlike radios with wooden consoles. Bakelite is a material based on the thermosetting phenol formaldehyde resin, polyoxybenzylmethylenglycolanhydride developed in 1907–1909 by Dr. Leo Baekeland. ...
The plastic era The availability of brightly coloured thermoplastics provided the freedom to produce free flowing designs. Some plastics are slightly translucent and are prized by collectors.

Early transistor sets Invention of the transistor led to many small radios that did not need a 15 second to 1 minute warmup time that many earlier vacuum tubed radios did. (Tube radios designed to run on batteries tended to have warm up times of a few seconds.) You just walked up to the radio, turned it on and heard the music playing over the radio almost instantly. They were available in many sizes from console to table-top to radios the size of your finger. Transistors are still used in today's radios, and are not as good quality as the radios that used vacuum tubes. Vacuum tube radios were hand-made by a factory worker and were unique to each company. Transistor radios are now made by computers and are alike between every company leaving them hard to service and highly generic.
