[sdiy] input buffer question

 > It has output short circuit protection (and, hence, the 1k output 
resistor we typically put in there is not strictly necessary, but I 
still do it anyway)

And well you should. Miss that 1K resistor out, or some other 'low' 
value resistor, and your output could well oscillate when driving a long 
cable.

Also, the op-amp's output may well be short circuit proof, but it may 
not 'like' being used as input.
