RCA 12BH7 – Black or Grey Plate – NOS Vintage Tube

Excellent choice for McIntosh amps and LA-2A style compressors!

The RCA 12BH7 is a premium dual triode tube prized for its musicality, clarity, and low noise performance. Whether you're running a vintage McIntosh preamp or a custom Hi-Fi build, this tube delivers rich tone with just the right touch of warmth and detail.

Choose your flavor:

  • Black plate: A touch warmer, with deeper midrange and a classic vintage feel.

  • Grey plate: Slightly more neutral and open, offering crisp articulation and balance.

Each tube is tested and guaranteed to perform. Perfect for McIntosh models like the C20, MX110, or any amp that relies on the 12BH7 for phase inversion or driver duty.

NOS, tested, and ready to sing.
Select your plate style and elevate your system.

NOS vs. ANOS vs. Test NOS

These designations are strictly used to describe the cosmetic condition of our tubes. All tubes we sell test identically, come with 100% life and are guaranteed to work in your device!

If you are picky about owning an original box or wanting a specific logo please reach out to us before purchasing.

  1. NOS (New Old Stock) Tubes- are 100% brand new vintage tubes in mint cosmetic condition with show zero signs of use. You should expect a legible logo and clean straight pins. An original box is likely but not guaranteed. 
  1. ANOS Tubes- otherwise known as “almost new old stock” tubes are basically new, but may show slight signs of use in cosmetic condition, such as a missing logo or slightly bent pins. An original box is possible but unlikely. 
  1. Test NOS Tubes- are used but still operating to specification with 100% life. These tubes are equal in function to NOS valves, yet they cost considerably less because they have cosmetic blemishes. If you plan to disappear your tubes into the back of an amplifier or do not care what the tubes look like, then this is cost effective choice. Blemishes and cosmetic imperfections do not affect tone…

Logos: Vintage tubes have a wide variety of logos printed on them. It is not uncommon to see a Mullard made tube with an RCA or GE logo, or a GE made tube with a Mullard logo. Your tube may come with a logo such are Heath Kit, Baldwin, Fisher, Hammond, Magnavox, Fender, Gibson, Silvertone, etc. but the true manufacturer of that tube will be correct to your order. If you are looking for a specific logo please reach out before purchase.

Our Standards:

  • All tubes are tested for microphonics and are guaranteed to work in sensitive audio applications
  • All tubes sold are guaranteed to have strong (to spec) NOS test scores with 100% life
  • All tubes are tested on a calibrated Hickok 539C, Maxi-Matcher, E-Tracer or other industry standard tube analyzers
  • Tubes are guaranteed for one year and can be returned within 30 days
  • Preamp tubes matched by gain and mutual conductance (Gm)
  • Power tubes matched by mA and Gm
