Can anyone tell me the 3 LEDs in the front and what they are/colors each one is? I broke them off trying to remove the PCB when it got hung on that weird light chute thing.
Awesome! I appreciate it.
Side note: Is it normal for these amps to get hot at idle? I noticed when energized in idle the 4 output transistors get too hot to touch after around minute (No heatsink) and it draws around 1.2 to 1.4amps at idle.
Clamped it all back together and it has sound, sounds fine. But the heatsink is getting pretty warm for little volume. Makes me feel like the output transistors are operating too far into the linear region.
When I got this amp, one of the four output transistors were shorted so i replaced all 4 of those and the two drive ICs from UTSource.
Checked VSS+12V, and its ok.

Not all distributors are reliable (selling legitimate parts). Sometimes they're hit and miss.
It's also possible that, to get the distortion numbers that they wanted, they have the deadtime so short that the slightest difference in parts (no two batches of parts are identical) can cause shoot-through, creating heating.
1.4 amps doesn't seem excessive.
You could try adjusting the deadtime resistors if you want the outputs to run cooler.
