Description

4 pieces of RCA 12AU7A tubes. As you’re probably aware, the A suffix on 9A miniature tubes indicated the low noise version for low level applications. While these 4 clear top tubes are not marked, they are clearly RCA manufactured.
Rather than making claims of “Diamond” or Platinum” matching, I’ve included pictures of each tubes test results in a Maxi-Preamp 2 digital tester. By making a few simple calculations, you can see these exceed many sellers’ standards for matching.
The price includes free shipping to any address in the lower 48 United States.
