of every mosfet transistor on my gottlieb system 3 driver board testing bad?

must be good, because they all did ( except for like 2)

OK, that being said. What the heck could have caused that.

there is one obviously bad chip on the driver board ( that had been previously socketed) and replaced with wrong spec. It is an LS instead of an 74HC273.

The auxillary driver board transistors all tested fine, but the 74HC273 voltage was different than the chips on the driver board.

Does anyone know what range the voltage should be on the 74HC273?
