It's listed as a sub on this web page
http://project.llaky.fi/audiocrew/vintage/tuberef.htm
More relevant, I also found this in a pdf file on the r-390A site:
"I went through the RF deck and individually swapped out tubes with at least
6 of
the same type and left the best S/n tubes in place... ( you guys should try
some of the CV-133 and 6135 tubes for the mixers..!!!) P.S. the note about
the
above mod is from HSN no. 5 March 1984...."
-- This was from Jordan Arndt
The file is at: http://www.r-390a.net/sensitivity-alignment.pdf
That extract is a the top of page 27.
