East End Hi-Fi are selling a Matched Pair of Sophia Electric Grade A SET Princess Carbon Plate300B Tubes. We are dealers for Sophia Electric, and these tubes have bee used in our demo amps. They have about 1500hrs on them. They are priced for the pair, and won't be sold separately.
Here's what Richard foster of HIFi+ had to say about the Carbon Plate:
"While I really enjoyed the Sophia Electric S.E.T. Princess 300B Mesh Plate Tube, the contrast to their equally enjoyable S.E.T. Princess 300B Carbon Plate is fascinating. While I felt the Mesh Plate had an openness, clarity and sweetness without euphonic colouration, I feel the dynamics of the Carbon Plate are more at play. The difference in perceived dynamic power displayed by the Carbon Plate brings it much closer in sound to the Euro Audio Team tube. It seems a more powerful tube than its sibling, with valuable additional headroom. It offered me all the positives
of the Mesh Plate without missing a beat, but with the added sense of directness, life and energy that comes from that wider dynamic range. This tube is extremely stable, holding rock-solid bias and delivering a direct, no-nonsense approach to music. Nor is there any glare, edge or thinness at any stage of operation – even when you push your amplifier to the brink. I found this to be an ideal tube for large orchestral works and heavily amplified rock music".
About Sophia Electric Carbon Plate 300B tubes
Note: S.E.T. Princess 300B tube models are
proprietary products of Sophia Electric Inc. Due to popularity of these
Princess 300B products, there are many look alike (or early ST model) in
the market trying to get
a share of success from those who can be easily switched.
We have been selling this S.E.T. Princess 300B carbon plate tube as
rigid plate 300B tube since April, 2006. So far the feedback from users
are very positive. It has totally different sonic characters compared
to the ever popular S.E.T. Princess 300B mesh plate model. Much like
carbon composite Allen Bradley resistors in a single ended amplifier,
this carbon plate 300B does have its carbon flavor and charm.
