I came across a box of tubes labeled 866A.The odd thing about them is there absolutely no mercury and no gettering - although there is clearly a getter mounted to one of the filament leads.Has anyone ever seen an 866A like described above ? I haven't tried these in any of my transmitters yet.

Thanks
Mark
