What is the 6N6P vacuum tube?

The 6N6P is a triode vacuum tube designed for line / otl applications. Low Rp driver. OTL capable..

What is a 6N6P substitute or equivalent?

Direct equivalents to the 6N6P include ECC99 / E182CC (Western near-equivalents). 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 6N6P?

Amplification factor μ ≈ 22, transconductance gm ≈ 11.2 mA/V, plate resistance rp ≈ 1.8 kΩ, max plate voltage 300 V, max plate dissipation 4.8 W, heater 6.3 V / 0.75 A.

Is the 6N6P still in production?

Production status varies by year and manufacturer. The current Amperatubes catalog classifies the 6N6P 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 6N6P sound like?

Low Rp driver. OTL capable.. 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.
