The most famous TRIODE, the MYTHICAL QUEEN, the Excellence, AUDIO FREQUENCY AMPLIFIER valve 1-2nd version, THE 2A3 FIVRE MONOPLATE: the AUDIO power amplifier!


Description

Extremely RARE nowadays, this is a mythical example of a "flat and ribbed" 2A3 FIVRE MONOPLAST direct heated (DHT) TRIODE; in general opinion, considered the most linear and best sounding Triode EVER produced! As everyone knows, the 2A3 power amp project is American, produced by the historic RCA but, undoubtedly, FIVRE has been able to create a tube that has surpassed its parent! With an absolutely unique and attractive image, this is the 1st or 2nd version, specifically carrying, in plain sight, the enormous "MINISTERIAL RADIO TAX" so it is possible that it was intended for government bodies but also for normal use in Civil radios. The performance of this valve 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 loudspeakers, inside a quality circuit, will give you UNIQUE sensations! Despite its more than ninety years of age, the valve is in excellent condition, as shown in the photos, all the filaments are bright and uniformly lit. Probably to be considered NOS but without original box. 96% TEST, practically FULL! ..Another UNIQUE OPPORTUNITY!!

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

PLEASE NOTE:

  • THE PRODUCT WILL BE SHIPPED "DOUBLE BOXED", OVERSIZED PACKAGING FOR MAXIMUM SAFETY!
