All 300B mesh 2.5V tubes come from the same factory. They are either labelled TJ, Full music, Sophia, and even New Sensor carries them.

TJ 300B tubes main dealer

Bottlehead also imports the 300B mesh plate tubes 5V and 2.5V.

Sophia electric.

There are also reviews posted on the tube at audioasylum.com and the 5V version was used in a 300B "shootout" at enjoythemusic.com.

Hello Reinhard,

Are you absolutely sure they're made in China ?
I thought these were made in Tchekia but I'm not 100% sure.
The idea is not new but was reintroduced by Alesa Vaic (former Tesla engineer)

From what I understand they're all individually branded for their respective distributors.

No, I am not shure that the tube is from China.
In the meanwhile I found out that the brand is TJ,
but not more information.

Additional Info is welcome.
