It delivers an unforgettable magical sound that is the trademark of Sophia Electric vacuum tube house sound. Along with Aqua II 274B tube, a new Classic II 300B tube was also debuted (photo below)."
The maximum current capability for Sophia Electric 274B mesh plate tube is 90ma, suitable for tube pre-amp and mono-block 45 single ended and 2A3 mono-block single ended. We would recommend Sophia Electric Aqua 274B rigid plate tube for 300B amplifiers. The maximum current capability for the Aqua 274B tube is 160ma.
Sophia Electric's proudest milestones since 2001: In 2001, Sophia Electric debuted the Princess 274B rigid plate rectifier to fill the gap left by the WE 274B. In 2002, Sophia Electric introduced a mesh plate design of 274B (above).
Kudos to Richard, the Aqua II 274B is an impressive accomplishment. If you can use a 274B rectifier in your amplifier, the Sophia Electric Aqua II 274B is an easy recommendation, and I heartily recommend you give one a try. I cannot imagine anyone being less than thrilled with its performance." User Experiences Reviewer Jeff Day:
In 2001, Sophia Electric debuted the Princess 274B rigid plate rectifier to fill the gap left by the WE 274B. In 2002, Sophia Electric introduced a mesh plate design of 274B (above). As much as we love the mesh plate 274B tube, the requirement of low capacitance of 10uf or lower at the first capacitor limited its potential use.
