Mesh plate 300B was developed in 2001. It’s one of the most matured tubes from TJ. It is popular for its warm sound. This was the one reviewed in EnjoyTheMusic.com. Mesh plate 300B is available in globe shape and ST (dome) shape.
300B/SE was developed in 2005. “Our panel agreed that the new carbon plate SE sounded much better than what we recalled from the mesh plate… Possibly I prefer the TJ-SE to the Western Electric in part because of its resemblance to the 211 in its ability to clarify texture, catch and release attacks, and maintain order in the harmonic structure” written by one buyer.
300B/CNE was developed in 2013 based on 300B/SE. The high is clearer while the base is preserved. It looks better too.
300B/Q was developed in 2017. It sounds as good as 300B/CNE while the plate is thinner and lighter.
There is also 300B/c/+.
Common issue of 300B/SE and 300B/CNE
Due to the high failure rate of export 300B/SE and export 300B CNE (while we are still using 300B SE and 300B CNE foe years without any problem), there is a high possibility that 300B/SE and 300B/CNE is prone to damge by international transit vibration.
Since the delivery safety is out of our control, we are sorry to announce that we cannot provide 12 month warranty for any graphite plate 300B, including 300B/Se and 300B/CNE.
