NEW - 2023
Sophia Electric S.E.T. Princess 300B mesh plate tube is the upper class model of the current 300B line (globe shape is still in production). This new tube is using the same 300B plate(as the globe 300B) with stronger plate structure learned from making the original princess tubes. It is a true 300B tube. It will work with all 300B amplifiers (Western Electric 300B direct replacement). The glass enclosure was from the Princess 206 tube for its unmatched sonic beauty. The shape of glass enclosure does make a major difference. Just thinking of violin's shape, if it gets changed to triangle, the sound character of violin will change for sure. Sophia Electric engineers have conducted many hours of audition and comparison. In the end the current shape of Princess tube glass enclosure is the most preferred choice sonically. It has more volume and more curved than the old ST. It is not the old ST came back rather it is a carefully crafted, researched new 300B model. The result is a 300B mesh plate tube with super clarity, low distortion and out of this world mid range fullness and liquidity. High frequency extension and sweetness is the first thing you would hear. Price is for 1 Pair - Quality Grade A - 1 Year Warranty
