| 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.
