Does anyone know why the new Western Electric 300b tubes continue to be delayed??


Just looking for more info than WE is sharing regarding the 300b restart. Have been on the pre order list since January and getting impatient on waiting.  Anybody have some validated info on when they will finally ship and what's holding them up?

Does anyone know what’s going on with the new WE 300B?  It’s been over a year since they took preorders.  
According to a poster on Audio Asylum (SET forum) they sent out the first new production tubes at the end of last week.
I have a quad set, but there not cheap, got them in the late 90’s and stored them away with low hours.
