I just wonder if they didn't change over to the EH at some point, especially since it seems the wxt isn't available anymore. I checked the couple of spare 447s I have in the shop right now and I have two different tubes. The build is similar, and both are definitely from the Reflector plant, but they aren't exactly the same. One is marked "GRN" and has the smaller getter like I've seen on the wxt, the other is marked "GRY" and has the larger getter like I've seen on EHs.
I guess I better check with Rich or Shawn this week and see what the current tube is. I'd hate to be telling my customers to use the Mesa tube if they want the EH, only to find out it's really the wxt!
