A friend uses the EML meshplate 45s. He really likes that tube a lot (he has many NOS variants, including old globe 45s).
I use both meshplate and solid plate EML 2a3s. Both are very good, particularly the meshplate tubes.
My only caveat is that the website lists some very specific operating conditions. The recommendations should be strictly followed. EML tubes cannot be pushed excessively hard--that dramatically shortens life (it shortens the life of all tubes, but, the EMLs seem to be a bit more delicate in that respect).
If you have any questions about the use of EML tubes in your particular gear, contact George Lenz at Tubes USA (US seller of these tubes). He is VERY helpful, forthright and conscientious.
