Description
 
The old original RCA BLACK-PLATE 12AX7's are very scarce, in fact, practically nonexistent in "NOS or even suitable NOS-LIKE shape". When you do find them they are usually worn down and half-life. Here is your opportunity to source phenomenal tubes with zero gas and zero heater-to-cathode leaks! American made 12AX7 tubes by RCA, the Premier World's Best manufacturer of 12AX7 extinct never to be made again tubes...
Made in USA in the 1950's RCA MATCHED-TRIODE
USA HIGH QUALITY 12AX7 TUBES. Quiet 12AX7
"PHENOMENALLY QUIET LIQUID SONIC TEXTURES"
LONG 17mm BLACK PLATE
OLD U.S.A."D" GETTER RINGS
MADE IN USA 12AX7 tubes have two (2) sides, that's why they are called "dual or twin-triodes"
There's no fooling around at the Tube Museum with meaningless claims like "tests strong!" WITHOUT SUBSTANTIATING TEST MEASUREMENTS, or some arbitrary number like "the tube test 82 with a minimum of 75" and no maximum stated! Wide gaps in mA and mA/V is not matched no matter how hard other sellers scream otherwise! Avoid those sellers! They don't show you the H-to-K (heater to cathode) leaks because they can't test for them, or hide the real facts from you!
TubeMuseum tested tubes always give you the test results in clear understandable FACTORY-DATA so you can compare with the real factory data sheets in mA and mA/V, just like the original factory data sheet specifications!
tube #1: 1,700/1,500 Gm (SOLD!)
tube #2: 1,600/1,500 Gm (SOLD! 6/25)
tube #3: 1,500/1,400 Gm (SOLD!)
