If shorted they usually read real low ohms ( pin5 -pin 3 )
or 5-4 etc. the zeners on the output (pin 4 ) could do it also.
If one is gone I would change both. ECG is same as NTE &
maybe easier to find. Also could back cross it to an
origional number ( not GE ) but dont know where to do it.
Any markings on them ???
