User Experiences

Sophia Electric’s latest blue glass 5U4G is a revolutionary product that offers superior high resolution, wider bandwidth (high frequency and bass extension) as well as musicality unheard from any of the vintage 5U4 family of rectifier tubes. Sophia Electric designers learned from making 274B and designed this tube to be 1/3 of 274b and 2/3 of 5U4G. As a result, It is a magical-sounding tube at less than 274B price and with wider acceptance in real-life applications.

The only trade-off is by trading for delivering high performance in sonics; it also limited its maximum current capability. The maximum current is at 200-220ma at 450V DC. It may not replace 5AR4/5U4 if only one rectifier is used for both channels in a push-pull 6L6/El34/KT66 amplifier. It would be the best if each channel has its own rectifier tube.

The life span is related to how hard to push it to its maximum specifications. If the application is within its design parameter then it would be a super reliable tube just like vintage 5U4 proved to be.
