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.

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?

I am going by memorey, but Cary once told me that I could use a meshplate in the SEI as long as I adjusted the bias down to the tube specifications. If the meshplates interest you, I would email the tube specs to Cary and get their opinion.

Going to try some AVVT valves, at least if my order get confirmed soon. These are AVVT 32B CL, which are the same as general 300B type, but with cool elements on the plates.
