E84Ls are an "enhanced" version of the regular EL84, rated for higher plate voltage and dissipation. They're a direct replacement for EL84s. Never listened to them myself.

I have a bunch of them, various origins.
Old European true E84L's, 6P14P-EV wich were Russian tubes with a slightly higher dissipation capabilities (+0,5 watt haha 12W for EL84 ; 13,5 W for E84L and 14 for 6P14P-EV, according to their respective datasheets ) and use a pair of AEG E84L's
These ones are obviously from the same plant than the 6P14P-EV, only a little more shiny surfaces in them.
Overall, these tubes give more power (enough to be heard i mean) or at least "almost clean headroom", and are a little harsher when pushed than EL84.
Beside thaht, they are EL84s
