On offer today one of these striking and ultra low hum devices.  This one shows a particularly pleasing high gain from its anode current test data.

The Mullard EF86 features the solid screen around the anode plate and rigid internal support. The anode has a solid screen design which covers the anode plate and is grounded. Some customers consider this screen better than the mesh screen design due to it exceptionally low levels of hum.
