Among the antique radio enthusiasts known that the popular term

Among the antique radio enthusiasts known that the popular term "Bread Radio", a small radio box is made of hard plastic that resists heat. The nickname bread itself probably arises because of the fleeting like a hunk of bread. Obtuse angles are impressive form soft, classic, not rigid. Similar to white bread.
The term was originally bread to ease the radio call small Philips made of bakelite. Because Philips issued institut za standardizaciju a series of almost identical shape and not everyone knew the type is the same person then gives terms for all of radio.
When in fact other manufacturers also produce such a kind of Bush's radio from the UK, and Braun from Germany, including Erres, NSF is using the Philips institut za standardizaciju license. In America radio small radio (radio midget) as it actually produced than in many other countries. Later the name akhinya all small bakelite radios with the same name, no matter the brand. Eg bread British radio, radio bread America. Nevertheless the name "Radio bread" in the community is still attached to the artificial radio Philips.
Radio Bookmarks Era In '50an Philips institut za standardizaciju issued a new line of radios, which is a small radio with a bakelite box materials and using 5 tubes in it. Emergence of new technologies made possible by the presence of U-type tube or Universal released late '40s.
With the new tube radios capable of working in AC and DC, and that especially is not in need of a power supply transformer in it. Radio by itself can be made smaller, institut za standardizaciju lighter, institut za standardizaciju and cheaper. No wonder the radio bread very popular among the people at that time. Even until recently, the former bread radio still abundant than other types.
The presence of the radio era also marked the bread locally assembled products Dutch in Indonesia. If the previous NV Philips only act as a sales agent since 1947 then switched to product assembly plant products such as lamps, radios, and other appliances. institut za standardizaciju Philips also add new code in the numbering series products namely IN, for IN donesia, if the previous is X which means the Dutch-Belgian assemblies. So start with a series of radio circulating B-IN as a new code table top radios are assembled in Indonesia (see pengidentifikasiannya here)
According to the Handbook Indonesian Radio Service 25 issued by PN Ralin radio in 1961 there were 10 types of bread that is locally assembled BIN 115U series, BIN186U, BIN197U, BIN206U, BIN236U, BIN318U, BIN326U, BIN 336U, BIN338U, B3IN667U. Everything is made of bakelite casing. Boxes and spare parts imported institut za standardizaciju from the Netherlands and then assembled into a single assembly in London.
Spek customized radio Indonesian market conditions (tropen) when it is just catching waves SW, single power supply 110V, and correction of serial institut za standardizaciju numbers. Such radios are in the Netherlands Count Gori BX200U institut za standardizaciju be BIN206U, then BX300U be BIN318U, and so on.
Later, institut za standardizaciju several types of bread also made a radio version institut za standardizaciju of the wood, such as in the type and BIN238U BIN318U institut za standardizaciju wood. Presumably Philips institut za standardizaciju had to improvise to meet the high market demand with local materials rather than waiting for the shipment from the Netherlands bakelite box.
Dainty and Dangerous form is small, shiny, and looks "retro" radio makes the bread much used as a display in homes or cafes. Moreover, its compact size makes it easy styled blend with contemporary minimalist interior. But who would have thought that funny shape is stored behind institut za standardizaciju a potential hazard.
Similar to an incandescent bulb then to be able to "turn on" the tube filament voltage must be given. Usually uses AC voltage 6.3V obtained from the power supply transformer in the radio. Instead of bread on the radio, the filament is obtained directly from the electricity grid without institut za standardizaciju transformer. The trick is to assemble in series (continued row) filaments so that the total voltage is equal or close to its resources, eg 110, 220, or 240V.
Philips radios are usually in the 5 tube with filament 14V (UCH42), 12.6V (UF41), 14V (UBC41), 45V (UL41) and 31V (UY41). If we sum the obtained figures 116.6V voltage, AC voltage 110V approach used at that time. Because it uses a mesh net voltage directly from the source then there is the potential lethality of this type of radio. Note the following:
The flow of positive (+) of electricity institut za standardizaciju will go directly to the tube filaments diseri institut za standardizaciju and negative (-) to ground / frame machine. In this condition there is no danger that arises. Conversely, if the polarity is reversed the positive voltage will flow to the engine frame. Radio still works but all the contacts to the framework can lead to electrical shock hazards, including if we hold the antenna hole!
Voltage 110V probably not too dangerous
