I remember reading this indicates a vacuum leak.
Anyway, the slotted columns have arrived. Very very excited, hehehe.
Took a $20.00 gamble on an unmarked slotted square graphite plate 6080WB - eBay seller stated he couldn't verify whether or not the tube would work.
It doesn't - Tube tester revealed a short on the filament pin. Not happy, but at least it's not megabucks down the tube.
Anyway - reason for the post. The getter flash is milky white. Do you think there is a relationship between the filament short and this?
Cheers and thanks
If the getter flash is milky white, the tube lost its vacuum and I would never put it in a tube tester.
I believe that other makers too made tubes for WE, but never used the same design for their own branded tubes.
Here are the different Bendix 6080 slotted plate styles.
The top tube has a smooth face edge and the bottom shows a clear sharp edge
