I recently picked up these tubes off ebay they were listed as NOS In Box Matched Pair GE USA 6EW7 Black Plate Vacuum Tube

however when they arrived here the tubes are 2 different sizes (see pic)


are they actually matched?

Those look like totally different tubes. I'm not familiar with this model, if they are the same thing just with different glass, they could be matched. Otherwise, they are not matched at all.

they both seem to have the GE mark on them and be the same model

GE mark isn't the easiest to see but they both look like the GE logo from whats left of it on both tubes

the model number is easy to see and they are the same


I did a quick google image search and GE did make 2 different glass types of these tubes
