2 Vintage Rare Military
RCA
5751
Rare Black Plate
Triple Mica Tubes
NOS
This tube was tested
in my Military Hickok Cardmatic USM-118B to make sure these were
perfect. All the tests were excellent. These tubes were made
in the U.S.A. by RCA, for the U.S. military. They will significantly improve the sound quality of your amplifier. These are the
military, low noise, black plate, triple mica, slanted "D" getter version. These are the military version of the 12AX7 tube.
This tube is getting scarce and is a high end tube used by most of the professionals. Great for guitar amps or any high end audio amp. This tube is what audiophile enthusiasts are looking for. It can be used as driver tube in your amplifier. The
tubes will come in the military brown boxes, as shown
in the photos. I can only read one code on the tubes, the other one may have come off in testing. I will pack carefully & ship very quickly.
RCA date codes: 5-30
Test
results: 75/78 & 77/78, whereas a minimum good on my Hickok Cardmatic USM-118B tester is 50/50. These are a matched pair.
