Marathon MX-280 Globe tube MESH PLATE

Here is a rare tube — a Marathon MX-280 Globe #80 rectifier tube featuring MESH PLATES construction!  Not only that, but each section tests very strong Emission, comparable to an NOS #80!

Mesh Plate Marathon MX-280 Globe rectifier tube

In 18 years of collecting, I do not remember ever seeing another Mesh Plates #80 tube.  Look at that Glow!  You can see right through the Mesh Plates into the filament!

It also has an Engraved-base which reads: MARATHON MX-280.
