[sdiy] crackle box

Hi yes LM709  is fine. Point is the 709 was a very early opamp with external
frequency compensation which is vital to the circuit
working. Substituting  for an opamp with internal freq compensation wont
work (I know ..I tried it :-)  ).  Luckily the LM709 is still in production
when I last checked.

cheers
