Please note that to use these to replace EL84 tubes, connections must be changed on the socket, these are not "plug in" replacements for EL84 - (the screen on EL822 is connected to pin 9 instead of pin 8, and pin 8 is the suppressor, which must be grounded or connected to pin 3)
We have adapters available to enable replacing EL84 with EL821.
