EXTREME and SUPERB as well as very RARE PAIR 5R4GY BRIMAR made in UK for FIVRE supply and distribution, double wave rectifier in power supply stage for AUDIO amplification!

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, genuine made in UK This is a wonderful and rare (especially in these conditions!) PAIR of 5R4GY by BRIMAR NOS/NIB commissioned by FIVRE that boxed and distributed them, specifically Italian Air Force (Tax Free Radio on the glass). It is a TOP of the range for its very particular design/internal structure, the extreme strength, the excellent suspension of the filaments, the BLACK ribbed and graphitated plates, 55 mm high, the thickness of the glass, the double suspensions for the vibration reduction, base in pure brown marble Bakelite and double DD-getter with huge Flashed-area. It is common opinin that this valve behaves, same responce, like the famous 274A and B Western Electric. Highly recommended for power supply stages in AUDIO circuit. Dynamic, fast, transparent sound and compact and clear bass.

EQUIVALENT: 5R4 = 5R4G = CV517 = 5R4G = 5R4GYA = 5R4GYB = 5R4WGY = CV684 = 5R4GYS - SUBSTITUTE: 274A and B

- World Audio Design 300B PSE
