this amp is stuck on protect mode.All outputs and power transistors tested fine no burn resistors or bad th .when i apply power to the amp it dosent feel like powering on .there is NO power on the gates of the irf44n none on even 1 of the 12 all gate resistors are good ,board was inspected and no burn tracks or any signs of previous repair or damage .it have the kia494 voltage contoroler im assuming this might be the problem but im just newbie seeking advice from the more competent

Post the DC voltage on all 16 pins of the 494. Place the black meter probe on the amplifier's ground terminal. Place the red meter probe on the point where you need to measure the voltage. Copy and paste the following into your next post.

Do you have a current limiter for your power supply?

If not, you'll need to insert a 10 amp fuse into the B+ line before you continue. Have all transistors tightly clamped to the heatsink before applying power.

Is there a Q1 with its emitter connected to pin 12 of the 494 and its collector connected to pin 5 of the 8 pin op-amp? If there is, pull it and power it up.
