Typically, a pair of 833As would be used in the final amplifier, plate modulated by another pair.
2.
Large water-cooled triodes may be used as the final amplifier in radio transmitters, with ratings of thousands of watts.
3.
Electrically, AN / ARC-5 transmitters use high-level final amplifier plate modulation, and the output tank circuit is shunt high voltage fed.
4.
The magnetic amplifiers required powerful pulses of heavy current produced by a transmitter-type vacuum-tube, of a type still used in amateur radio final amplifiers.
5.
The original FCC output power limitation for CB radios was " 5-watts DC input to the final amplifier stage ", which was a reference to the earlier radios equipped with tubes.
6.
After the light had passed through the final amplifier and spatial filter it was then used for experiments in the "'target chamber "', lying at one end of the apparatus.
7.
The FCC simply rounded-up the old " 5-watts DC input to the final amplifier stage " specification to the new " 4-watts output as measured at the antenna connector on the back of the radio ", resulting in a far simpler and easier specification.
8.
In military equipment, the 807, and 1625 with rated anode dissipations of 25 watts and operating from a supply of up to 750 volts, were in widespread use as the final amplifier in radio-frequency transmitters of up to 50 watts output power and in push-pull applications for audio.
9.
The first transmitters for 2FC, 5CL and 4QG were made by AWA with power of 5 kW ( note that until about 1931 in Australia, transmitter powers were defined in terms of DC input to final amplifier, typically about 3 times that of the power into the antenna; thus power today would be stated as about 1.7 kW ).
10.
There are two LFOs ( " LFO1 " and " LFO2 " ) with a user-assignable wave shape and frequency modulation source . " AMPENV " is the main ADSR ( attack-decay-sustain-release ) control source for the final amplifier in a layer and has multiple attack, decay, and release segments . " ENV1 " and " ENV2 " are bipolar envelopes, and " ASR1 " and " ASR2 " are two more unipolar envelopes.
