Hi,
thanks for your reply.
If you read the Datasheet of  lm709 at 
http://www.national.com/ds/LM/LM709.pdf
you will see that the lm 709 cn/14 and lm 709 cn/8 have same specifications 
and data and that, if you mount the 8 pin version starting from the 3rd line 
of the of the 14 pin socket (pin 1/8 --> pin 3/14, 2/8 -->4/14, ....pin 
8/8 --> pin 12/14) there is a correspondence pin to pin.
Can you confirm it ?
thanks
