Description

Among the "double diode" voltage rectifier tubes, undoubtedly, the 5R4GY, like the 5U4G and the GZ34, was and is among the best, best known and most used, ever produced; especially in power supply circuits for AUDIO amplification. The TOP of the range for this valve is certainly the production of BRIMAR, genuinely made in the U.K. This is a wonderful and rare (especially in this condition!) PAIR of 5R4GY by BRIMAR NOS/NIB commissioned by the FIVRE which boxed and distributed them, specifically the Italian Air Force (Exempt Radio Tax on Glass). It is a TOP of the range for its very particular design/internal structure, the extreme sturdiness, the excellent suspension of the filaments, the 55 mm high plates with BLACK and graphite ribbed finishes, the thickness of the glass, the double suspensions for the vibration reduction, pure brown marble Bakelite base and double D-D-getter with huge Flashed-area. It is commonly believed that this tube behaves like the famous Western Electric 274A and B. Highly recommended for power supply stages in AUDIO circuitry. Dynamic, fast, transparent sound and full-bodied and clean bass. PAIRS Balanced and Matched.

EQUIVALENT: 5R4 = 5R4G = CV717 = 5R4G = 5R4GYA = 5R4GYB = 5R4WGY = CV684 = 5R4GYS - SUBSTITUTE: 274A and B
