Demo Pair: Sophia Electric Princess 300B mesh plate tubes
We found this pair of Sophia Electric Princess mesh plate 300B tubes in a demo amplifier. We have re-tested the tubes and confirmed these two tubes are matched. We also played these tubes in our 300B amplifier and the sound is amazing! The pins have shown wear due to age and corrosion. The white mark between the base and the glass enclosure is glue residual.
One of the tubes has a small loose piece of glass inside the glass enclosure, which will not impact its sonic performance nor its lifespan.
