Bill -

The two sources that I would check at RF Parts (who sell Taylor - and others)
http://www.rfparts.com/tubetran.html

and Tom's Tubes.
http://www.tomstubes.com/

Please check the 572B advisory on RF PArts web site regarding Svetlana 572B tubes

The 572B tube is now only made in China and I think can be found under two names, Taylor and RF Products. The Russian version comes from existing stock and is no longer in production there. You might locate NOS (new old stock) of American/European brands, but they are getting dated.

The confusion is probably caused by similarity in names.

The Dentron amplifiers of the 1970's actually shipped with 572Bs made by CETRON, who no longer makes them.

I owned several Dentron amps back then, including the popular Clipperton-L (4 x 572Bs) and all the tubes came from CETRON.

THNKS folks, we appreciate everyone’s information and suggestions.
Basically we agree with WB2WIK's comments regarding tubes MFG. by CETRON for DENTRON.
We are happy to have 2 matched pairs for our SB-200’s
