Purpose, brief description

The output miniature pentode - EL84 is used to significantly increase the power of low-frequency signals in the final stages using a single-stroke or two-stroke circuit. Radio tube production began in 1954, when the Philips company released an experimental batch of EL84 electrovacuum devices with the goal of replacing the outdated EL41 pentode in inexpensive radio receivers.
