Description

This quality of vintage RCA 5814A (military grade of the 12AU7) black plate 2 tube set is a rare find for collectors and enthusiasts of vintage audio equipment. Made in the United States, these preamp tubes are platinum (perfectly) matched on a TV3B, ensuring optimal sound quality and balance. The RCA brand is known for its high-quality audio products, and this set is no exception. These tubes are perfect for those looking to complete their vintage audio collection or those seeking a unique sound for their music. These are for the person that can appreciate listening to a perfectly matched pair of tubes. Both tubes and triode sections are the same in transconductance: 2350 micromhos (the new level is 2200). A better match can not be had and a match of this level is very rare.
