In the old days the mesh plates were woven from wire; now they're punched (cheaper); these look rather coarsely punched. A disadvantage I remember is a lower max. dissipation versus the solid anode counterparts; other than that it has theoretical advantages (out there somewhere on the web) and more than a few seem to prefer the sound of mesh plate 300B and such over the solid plate versions. Only one way to know if - as a matter of speech -punching those el34 plates was a marketing afterthought or fruitful engineering...
