[R-390] Tubes new or used?

[Cecil Acuff]

There are brand spanking new 3TF7 tubes available from the manufacturer. 
But they are expensive!  Not sure of the price but someone posted recently 
about it....I just don't remember.  There are also what I would think are 
New Old Stock Military 3TF7's available from time to time on Ebay.  Saw one 
just the other day...may still be there.
So the answer is yes....as a matter of fact you can purchase every tube in 
the R-390A new...they may be 20 years old but new..

Cecil....
