WTB Emission Labs EML 20A Mesh driver tube pair

Wanted to buy
The 20B should work fine in place of the 20A mesh plate. I built a run of line stages about 7 years ago that originally used the 20AM (20A mesh plate) and switched to the 20B in these units last year. It is very quiet, offers the same mu and generally is as good or better than the 20A. It is also more reliable.

The Rp is significantly lower in the B but otherwise is pretty much a direct swap. (The reverse is not true) You can check with EML for confirmation
