What is the EL95 vacuum tube?

The EL95 is a pentode vacuum tube designed for power applications. Compact output..

What is a EL95 substitute or equivalent?

Direct equivalents to the EL95 include 6DL5. These share the same pinout and operating envelope, so they can usually be swapped without circuit changes — though batch-to-batch variations between manufacturers (NOS vs current production) may shift the sonic character noticeably.

What are the key specifications of the EL95?

Amplification factor μ ≈ 17, transconductance gm ≈ 5 mA/V, plate resistance rp ≈ 80.0 kΩ, max plate voltage 300 V, max plate dissipation 6 W, heater 6.3 V / 0.2 A.

Is the EL95 still in production?

Production status varies by year and manufacturer. The current Amperatubes catalog classifies the EL95 as Common availability. NOS (new-old-stock) examples from RCA, Mullard, Tung-Sol, GE, Sylvania and Telefunken trade among collectors; modern production where it exists comes mostly from JJ Electronic, Electro-Harmonix, Tung-Sol (New Sensor), Genalex, and a handful of small-batch makers.

What does the EL95 sound like?

Compact output.. Sonic character also depends heavily on the circuit operating point, the surrounding tubes in the stage, and the output transformer when present — use the interactive loadline calculator on this page to explore the trade-offs.
