Working on a Williams 1978 World Cup. Checking voltages and on 3J3 of the power supply I am not getting the 28 VDC on pins 6 and 7. Checked 3P2 have 33 VDC there. Check fuses all are good. Check the bridge rectifiers and om's reading was good between 400 - 600. Have all the other correct voltage on the power supply. Any ideas of what would cause this?

Thanks
