Tommy: We checked the voltage on IK04 & IK05 witch is the STK's and all are on the money. Do you know the location of those resistors and Zeners? I have the schmatic.

There are also a couple of Zeners that can be a problem. Usually it is the coupling resisors. They will be a low value...something like 1.8 ohm or 220 ohm.
