What is the RV12P2000 vacuum tube?

The RV12P2000 is a pentode vacuum tube designed for preamp / rf applications. Wehrmacht universal pentode. Historic..

What is a RV12P2000 substitute or equivalent?

Direct equivalents to the RV12P2000 include None. 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 RV12P2000?

Transconductance gm ≈ 1.5 mA/V, plate resistance rp ≈ 1000.0 kΩ, max plate voltage 250 V, max plate dissipation 2 W, heater 12.6 V / 0.075 A.

Is the RV12P2000 still in production?

Production status varies by year and manufacturer. The current Amperatubes catalog classifies the RV12P2000 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 RV12P2000 sound like?

Wehrmacht universal pentode. Historic.. 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.
