Amp is stuck in protect mode and I can’t figure out why. I apply power to the amp and no current draw or red light. I measured the voltage on Pin 4 of the TL494 and read 4.98 volts. I ground pin 4 and the amplifier comes on and draws 9+ amps of current. I realized it’s a short somewhere so I check the output section and not a single transistor, diode or mosfet is shorted. What have I overlooked?
