rectifier tube การใช้

• Early tube amplifiers had power supplies based on rectifier tubes.
• For example, in older equipment, this may cause arcing in rectifier tubes.
• In many designs the rectifier tube had a tap on the heater to power a dial light.
• Rectification in the original Bronco is via a single 5Y3GT rectifier tube, used by Fender since the early 1950s.
• The 0Z4 was a gas-filled rectifier tube commonly used in vacuum tube car radios in the 1940s and 1950s.
• Zenith used a selenium rectifier of later versions of the T / O, replacing rectifier tubes used on the earlier models.
• Circuit board degradation is often seen on inexpensive tube radios produced in the 1960s, especially around the hot output and rectifier tubes.
• What makes the Valpreaux distinct from the MkIII is that it features a significantly larger power transformer which powers a 5 volt GZ34 rectifier tube.
• Note that the A battery did not need to heat the rectifier tube because, when operating from the batteries, the rectifier was not needed.
• The LTD came equipped with the original 5AR4 rectifier tube, and four Jensen P10R reissue alnico speakers, which was period correct for the original amp.
• This final 1950s Tweed Bassman model product line included a change from the 5Y3 to the GZ34 rectifier tube, as well as a modification within the Presence control circuit.
• With the invention of the rectifier tube, which made it practical to power radios by electrical outlets, in 1928, Philco decided to get into the booming radio business.
• Tom Fletcher of the QRS Company was so impressed by Lear s radio set designed around a QRS rectifier tube that he hired him, offering 60 % more pay than Universal Battery.
• In 1919, the book " Cyclopedia of Telephony & Telegraphy Vol . 1 " described an amplifier for telephone signals that used a magnetic field to modulate an arc in a mercury rectifier tube.
• It was a conventional full-wave rectifier tube with two anodes and one cathode, but was unique in that it had no filament ( thus the " 0 " in its type number ).
• In tube sets, a one or two-turn filament winding is located on the opposite side of the core as the HV secondary, used to drive the HV rectifier tube's heater.
• The Pioneer III cars suffered from a low capacity main transformer as well as gearbox issues and a complex propulsion system that coupled highly sensitive mercury arc ignitron rectifier tubes with an inefficient DC resistance motor controller.
• RCA and other manufacturers later introduced many similar 5V rectifier tubes of both higher and lower current and voltage rating, including the 5V3, 5W3, 5X3, 5Z3, 5U4, 5Z4, GZ32, and GZ34.
• In fact, Fender used an earlier version of this rectifier tube in the 1940s ( the 5Y3 ) before it was phased out by manufacturers in the early 1950s to be replaced by the more electrically robust 5Y3GT.
• There were even a few " AA4 " designs, usually midget sets, only usable in strong-signal metropolitan areas, because most had no IF amplifier ( although some replaced the rectifier tube with a selenium rectifier ).
