Can you  imagine tube amplifiers laying on the floor of the Atlantic ocean   
amplifying telephone carriers.



Dave and others:
 
For an extremely informative look at the vacuum technology through the  
years, get a copy of the book, "75 Years of Western Electric Tube  Manufacturing," 
by Bernard Magers.
 
I paid 23.82 for a new copy plus shipping from Antique Electronics Supply,  
LLC in Tempe, Az.! Their phone number is 480-820-5411.
 
I was fortunate to live through the exciting years of 1960 through 1989 as  
an employee of Ma Bell both in plan operations and later engineering  
departments. In operations we used many of the very original vacuum tubes  constructed 
by Bell Labs and damned if they weren't still In Service!
 
I remember in 1980 writing the AT&T specs for the demise of the South  Bend 
Scoot street AT&T office. We powered down old vacuum tube amplifiers  still 
using the 102 series vacuum tube amplifiers that were carrying voice  traffic on 
the New York to Chicago cables!
 
Another source of fascinating reading is the Principles of Electricity  
applied to Telephone and Telegraph Work, published by AT&T. For its  Employees!
 
Mom's calling for supper. Gotta go.
