Hello,
I've seen on Sophia Electric site that they sell a custom 300B mesh
plate tube. Has somebody tried it? I asked for technical specs. but
got no direct answer (they told me "the datasheet comes with the
tubes"), so I was wondering if 280-300 dollars for a pair is a fair
price.
BTW, this is a link with a photo of the tube:

Thanks for your answers,

Kamox.

Good question, also interesting to know would be : what rectifier tube
matches it the best ?
