Console television set. A console television is a type of CRT television most popular in, but not exclusive to, the United States and Canada. Console CRT televisions are distinguished from standard CRT televisions by their factory-built, non-removable, wooden cabinets and speakers, which form an integral part of the television's design.
The flyback transformer operates CRT-display devices such as television sets and CRT computer monitors. The voltage and frequency can each range over a wide scale, depending on the device. For example, a large color TV CRT may require 20 to 50 kV with a horizontal scan rate of 15.734 kHz for NTSC devices and 15.625 kHz for PAL devices.
Three types of projection systems are used in projection TVs. CRT rear-projection TVs were the earliest, and while they were the first to exceed 40", they were also bulky and the picture was unclear at close range.

The Precision CR30, Sencore CR-70 and Jackson 707 are some of the CRT testers that are capable of testing the 7JP4, 3KP4 and other electrostatic deflection CRTs. Since the availability of these CRT testers is very limited, the prices for such testers are steep, so many restorers test these CRT's on a working TV set that used electrostatic CRTs.
