[R-390] TR: Fake WE 403's on ebay?

[Jacques Fortin]

Tube counterfeiting exists since the first ones were made.
Only experienced people can tell if a given tube is a fake or not.
Some manufacturing details of the originals simply cannot be reproduced.
I agree with Perrier that the genuine WE tubes are marked parallel on the long side, and the yellow lettering is very specific too.
The Northern Electric ones, made in Montreal, were marked the same.
