The TMC TIS-3 is such a unit. Uses 12AX7's and the like. TIS means  
Tone Intelligence System.  (There may well have been a TIS-1 and TIS-2  
but I am unfamiliar with them.)  All TMC stuff was military grade and  
carried military nomenclature in many cases.

See John Poulton's site:
http://www.virhistory.com/tmc/tmc_pages/index.htm
for a manual.

The Northern Radio Company also produced a tube type tone generator.   
(See the same page for a link to info on their products.)

John's main TMC list is at:
