Pin 2:4.62
Pin 3:0.06
Pin 4:4.96
Pin 5:1.50
Pin 6:3.33
Pin 7:0.00

Pin 12:13.84
Pin 13:4.97
Pin 14:4.97
Pin 15:4.97
Pin 16:0.00
I have no voltage present on the gate leg of the power supply fets..
Any ideas?

Pin 4 of the 494 goes thru some resistors and connects to the small yellow transformer..
Pin 5 of the 339 goes thru a resistor then a diode and goes to the small yellow transformer..
I get no voltage on the diode that connects to the small transformer..
Do thoose transformers go bad or do i need to look further back in the circuit?
