Kr Enterprise 300b xls non bottle shaped?


I've been mislead by a seller to buy those KR 300b xls tubes that are non bottle shaped.

Contacting KR Audio, they say those tubes were made by KR Enterprise whose out of business since 2000....!

Now I don't even know their spec and if
they can be played on my Sati 520b amp.

Can anyone help?

My understanding is that KR Enterprise went under some form restructuring and re-emerged as KR Audio. KR Audio should have the info you are looking for.
