Pins 8 and 11 of the 494 are tied together and should have B+ voltage on them.It would be unusually for this to happen.

Check to see if Q26 and Q27-2N4403 have drive on the base. If yes one of the drivers is bad,or a trace to the gates or gate resistor is open. If no follow trace back to the PWM card.
