Product information

Sophia Electric™ 274B tube is a premium rectifier tube for a 5U4/5R4/5AR4* direct replacement with 3X longer plate structure, thus it has a deeper, wider soundstage and even smoother sound than Mullard 5AR4.

Historically, WE 274B was designed for the WE300B amp, the current NOS WE 274B is $1000 each unit (see Vacuum Tube Valley magazine), the used one can be as high as $500 on Ebay. According to a recent test, this Sophia Electric™ 274B tube outperforms the NOS WE 274B by higher current capability, which translates into better bass, dynamics, and deeper soundstage.

The sonic difference comparing to conventional 5U4, 5AR4*, 5R4 is far bigger than any cable upgrades combined in a high-end system.
