As far as I know, there are four manufacturers in China produce the 300B. They are ShuGuang, TJ Music, LinLai, and GuiGuang. Interesting enough each of them have several types of 300B tubes with different price range from hundred to several hundred a piece.
I am very curious how they are different from each other???

I think a lot of us are equally curious about how they all compare sound wise. At least some of the options are affordable.
Doesn't interest me any more since I converted to 2a3, and prefer the sound.
There was a previous long thread on this which didn't get anywhere. Almost nobody has bought enough of a selection of 300b tubes to be able to compare them. The types that failed gave some information, but since a lot depends on how hot you run them even that wasn't so useful.

I ordered a couple of them. There are strange scratches on both tubes inside the bottom of the glass, I can see them form the inside too.
Seller said "The tubes are made by hand. It is hard plastic hit marks. Not the glass cracked, so you can use it with confidence."
What is it?
