Can you supply the date codes to backup that statement? My sources state
they are just a later batch released from surplus and the DXE reviews are
mixed....only 3 reviews going back a year or more do not give me a warm
feeling.
Also DXE is drinking the same Cool Aide as Svetlana which is just one of
many reasons I wont buy anything from them.
The GU-74B is strictly a 600W Pd tube and is also specified for SSB service
in the REAL specs....and not 800W.
Run 'em easy and dont believe the liars and cheats.

From personal experience, I would recommend DXengineering for the GU-74b.
These are from a new production run by Svetlana and they work great but YOU
MUST reset the bias when changing tubes or they may not run linear.

So, Carl, where would you suggest us cheap, constantly crying, hams get new,
or
at least new-old-stock Eimac 4CX800's and 3CX800's ? Lotsa luck.

Unlike Eimac, Philips and similar manufactures who design tubes for CCS
service along with plenty of reserve emission to compensate for aging.
that
tube and most amateur service Chinese are run at the edge. And cheap
hams
cry constantly.
