What is the E130L vacuum tube?

The E130L (E130L / 7534) is a pentode vacuum tube designed for power (se/pp) applications. Extraordinary wideband pentode. Massive gm..

What is a E130L substitute or equivalent?

Direct equivalents to the E130L include 7534. 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 E130L?

Amplification factor μ ≈ 6, transconductance gm ≈ 27.5 mA/V, plate resistance rp ≈ 10.0 kΩ, max plate voltage 900 V, max plate dissipation 27.5 W, heater 6.3 V / 1.7 A.

Is the E130L still in production?

Production status varies by year and manufacturer. The current Amperatubes catalog classifies the E130L as Rare 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 E130L sound like?

Extraordinary wideband pentode. Massive gm.. 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.
