Description

Extremely RARE nowadays, this is a legendary example of direct heated TRIODE (DHT) 2A3 FIVRE SINGLE PLATE "flat and ribbed"; in general opinion, considered the most linear and best sounding Triode EVER produced! As everyone knows, the design of the 2A3 power amp is American, produced by the historic RCA but, undoubtedly, FIVRE was able to create a tube that surpassed its parent! This example is the 2st version, a 2A3 Monoplate in original BOX although not perfect, in excellent physical and electrical conditions, probably NOS with 96% emission. The performance of this tube is well known, extremely harmonious, sweet and engaging, as well as full-bodied and impactful bass when the recording allows it. Low power applied to high sensitivity speakers, within a quality circuit, will give you UNIQUE sensations! Despite being over ninety years old, all the filaments are bright and evenly lit. Virtually FULL TEST still specified in the description at an exceptional price!

EQUIVALENT: VT-95 = CV1831 = KX2A3 = NU-2A3 = 2A3H = 38213 = 2A3-B = 2A3-C = 5930 & SUBSTITUTE: 45 = UX245
