[Heathkit] TV-7 Data for Compactrons

[Richard Knoppow]

     I think there is a spread sheet at BAMA but can't 
connect to it right now.  There are compilations of settings 
for many tubes including both 9 and 12 pin Compactrons 
available on the web. If not at BAMA (look under military) a 
google search will find them. The sheet also includes wiring 
information for the two sizes of Compactron sockeds to 
octal. Both sockets and plugs are available but may take 
some searching to find.  There were adaptor sockets made for 
the TV-7 but I doubt if many of the testers have the 
complete original accessories.
     One of the spread sheets also has a chart for 
translating from the TV-7 meter readings to the actual 
transconductance.
