300B/c/+ is much longer than the usual 300B, can play directly on some 300B amp.
These two tubes are not very well matched but both tubes are performing well, suitable for systems that left and right channel volume can be adjusted separately. One tube is printed blue while the other is red. Printings can be removed to have identical appearances.
Each TJ tube has a built-in serial number and is tested in our workshop before shipping out, therefore we are confident to offer a 12-month warranty. Since this is not our regular stock item, the warranty will depend on the manufacturer’s stock availability and processing time for replacement may take up to 3 months.
Curve tracing testing is being used because it can reveal problems that are hidden in other tests.
History of TJ 300Bs
Mesh plate 300B:
Developed in 2001. Warmer sounding than other TJ 300Bs. Available in globe shape and ST (dome) shape. This was the one reviewed in EnjoyTheMusic.com. Good value for money.
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”
Developed in 2013.
Developed in 2017.
