What is the 6N30P vacuum tube?

The 6N30P (6N30P / 6Н30П) is a triode vacuum tube designed for preamp / driver applications. Super tube. Authoritative linearity..

What is a 6N30P substitute or equivalent?

Direct equivalents to the 6N30P include ECC99, E182CC. 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 6N30P?

Amplification factor μ ≈ 15, transconductance gm ≈ 18 mA/V, plate resistance rp ≈ 830 Ω, max plate voltage 250 V, max plate dissipation 4 W, heater 6.3 V / 0.825 A.

Is the 6N30P still in production?

Production status varies by year and manufacturer. The current Amperatubes catalog classifies the 6N30P as Moderate 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 6N30P sound like?

Super tube. Authoritative linearity.. 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.
