In common with all 'E' prefix tubes, using the Mullard–Philips tube designation, the EL34 has a heater voltage of 6.3 V. According to the data sheets found in old vacuum tube reference manuals, a pair of EL34s with 800 V plate voltage can produce 90 watts output in class AB1 in push–pull configuration. However, this configuration is rarely ...
The data sheet information supplied by the tube manufacturers' design-centers list the typical operation of an audio output stage for a single 6V6 as producing about 5W of continuous power, and a push-pull-pair about 14W.
This electron tube was intended for use in very high power medium-frequency broadcast service and VLF communications equipment and as a pulse modulator (as a switch tube). The EIA (Electronic Industries Alliance) designation 8974 was assigned to this as it became a standard product. The initial technical data sheet was printed in July 1971.

Philips Valve Data Book, Australia, 1954 The type 955 triode " acorn tube " is a small triode thermionic valve ( vacuum tube in USA) designed primarily to operate at high frequency. Although data books specify an upper limit of 400–600 MHz, some circuits may obtain gain up to about 900 MHz.
In common with all 'E' prefix tubes, using the Mullard–Philips tube designation, it has a heater voltage of 6.3V. It can produce 17W output in Class AB1 in push–pull configuration. Many guitar-amplifiers routinely run EL84 tubes in excess of 400VDC, with the Traynor Guitarmate reportedly putting out 25W RMS with 2 EL84s in a push–pull ...
The 4-1000A is a relatively large glass tube with an overall height of 9.25 inches and a diameter of 5 inches. It is designed to operate with its plate (anode) at an orange-red color due to the "getter" being a zirconium compound on the anode structure which requires a great deal of heat to be effective.
In electronics, the 300B is a directly-heated power triode vacuum tube with a four-pin base, introduced in 1938 by Western Electric to amplify telephone signals. It measures 6.4 in (16 cm) high and 2.4 in (6.1 cm) wide, and the anode can dissipate 40 watts thermal.
