Extremely RARE nowadays, this is a mythical example of a direct heating TRIODE (DHT) 2A3 FIVRE MONOPLACCA "flat and ribbed" ; in general opinion, considered the most linear and best sounding Triode EVER produced! As everyone knows, the project of the 2A3 final is American, produced by the historic RCA but, undoubtedly, the FIVRE has been able to create a tube that has surpassed its parent! With an absolutely unique and attractive image, especially the 1st version with its fascinating label / logo called "Aquila"! The performance of this tube is impressive, extremely harmonic, sweet and engaging, as well as full-bodied and impactful bass when the recording calls for it. Low power applied to high sensitivity speakers, inside a quality circuit, will give you UNIQUE sensations! Despite its over ninety years, the valve is in amazing condition, all filaments are bright and uniformly lit. Nearly NOS condition (?). Inside the tube is a tiny piece of vacant glass which has absolutely no effect on electrical operation and acoustic performance. UNIQUE OCCASION!!
