linear amplifier वाक्य

It is ironic that many " faulty " Audions, which had lost their ability to demodulate radio signals due to gas absorption, had actually turned into crude linear amplifiers ( which was why they lost their demodulating ability ), but nobody realized this at the time.
After Spider's activities with REACT are seriously disrupted by a gang of local kids holding a frivolous conversation on Channel 9, which is reserved for emergency communications, he decides to go on a singlehanded county-wide crusade to shut down illegal CB stations, such as those using unlawful linear amplifiers.
The 807 is not a good choice of tube for typical Ultra-Linear amplifier circuits, as the maximum screen voltage at 300 V is less than half the maximum plate voltage of 750 V . A possible solution is to use an output transformer with a separate ultralinear screen winding, such as the Acrosound TO-350.
Along with transceivers and separates, the 4-Line included a set of matching accessories including the L-4 linear amplifier, C-4 control console, W-4 and WV-4 power meters, transmit and receive converters for the 50 MHz ( 6 meter ) and 144 MHz ( 2 meter ) bands, and antenna impedance matching networks ( tuners ), the MN-4 and MN-2000.
