Description	Output pentode Launched early 1953; Equivalent type: 6BQ5 Predecessor: EL41 Successor:~ECL86 The very successful EL84 is the last developing step from EL3 via EL41 to the final point of radio output pentodes. It's dissipation power was increased from 9 to 12 watts, giving an output power of 5.7 watts, which was seldom utilized. The sole later launched ECL86 may not be considered as a true successor as it is a multiple beam-power-tube with again only 9 Watts. [J.R.18Feb2003] Text in other languages (may differ)
