CARY CAD 300sei 300B tube rolling/ultimate search


Looking for some feedbacks about 300B tube rolling on Cary amp please.
So far I am using Sophia's mesh plates and KR Audio ( tubular, old production run )

Interested in:

1. NOS TESLA - very rare and most probably cant be found, except the copy of it EAR.

2. Svetlana C logo - seems to be a difference in run before year 2000 and after, where 2 companies make them now: St.Petersburg and Saratov, but how differ are they?

3. Genalex

There are many others, so post as much as you want please.

Also your most loving combinations of 6SN7 + 300B are very welcome.

Emission Labs should be on your list - For a little more punch and dynamics try the EML 300B XLS. A touch more detail and sweetness try the EML 300B-meshplate.
@Brf
Thx for your replay, will do. I believe they make them in Czech Rep as well as KR, isnt?

ps Little change, I ment EAT and not EAR of course, sorry guys:)
Yes, EML tubes are manufactured in the Czech Rep. Here is a link to their NA distributor. http://www.jacmusic.com

Another 300B tube that I like very much but is getting harder to find is the AVVT 300B SL-C37.
I just got the answer from Jac, where he thinks that I cant use EML 300B Mesh in my Cary and the best option would be the 300B - XLS.

Any idea about using mesh pls?
