Zenith, and to a lesser extent Motorola, avoided this problem by continuing to use hand wired chassis in all their vacuum tube equipment. Zenith kept circuit boards out of their televisions until the Chromacolor line of the early 1970s, and even then used them only with solid state components, mounting the four tubes used in the Chromacolor "4 ...
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again.
Distributed Mode Loudspeaker (DML) is a flat-panel loudspeaker technology, developed by NXT, [1] in which sound is produced by inducing uniformly distributed vibration modes in the panel through a special electro-acoustic exciter.
EM34 tuning eye EM84 tuning indicator. A magic eye tube or tuning indicator, in technical literature called an electron-ray indicator tube, [1] is a vacuum tube which gives a visual indication of the amplitude of an electronic signal, such as an audio output, radio-frequency signal strength, or other functions.

The Zenith Flash-Matic was the first wireless remote control, invented by Eugene Polley in 1955. It had only one button that was used to power on and off, channel up, channel down, and mute. It had only one button that was used to power on and off, channel up, channel down, and mute.
Paul Wilbur Klipsch (March 9, 1904 – May 5, 2002) was an American engineer and high fidelity audio pioneer, known for developing a high-efficiency folded horn loudspeaker. Unsatisfied with the sound quality of phonographs and early speaker systems, Klipsch used scientific principles to develop a corner horn speaker that sounded more lifelike ...
Zenit 122 Zenit-4 with leaf shutter Zenit-16 with vertical travel shutter. The first attempt to make high-end professional camera by KMZ was the Start in 1958. This camera had a full set of shutter speeds (from 1 sec to 1/1000), a lens with an automatic diaphragm in a unique breech-lock mount, and even a knife for cutting-off part of the unexposed film.
The astronomical meridian is also determined by the zenith, and is defined as a circle on the celestial sphere that passes through the zenith, nadir, and the celestial poles. A zenith telescope is a type of telescope designed to point straight up at or near the zenith, and used for precision measurement of star positions, to simplify telescope ...
