Hello. I appreciate the suggestions related to the subject. What I have found as an anomoly is that pin 7 of U4 is at 4.94vdc, as is pin 1 of U5. Both of these pins are clocking (CLK) I/O pins for U4 and U5. A steady 4.94vdc is abnormal. I also looked more carefully at T5. The four green wire turns are situated such that there are four red wire turns on the 2-4 side and seven red wire turns on the 1-3 side. The green and red wires are in the correct holes. I can find no problems with the thermister nor can I find any soldering problems. Any suggestions at this point would be appreciated. The alignment steps up to VCO alignment and the step subsequent all check out perfectly. Thanks.
