Nuforce STA200 Dead Channel - Tech Help Please

After connecting my STA200 to my speakers & turning on the power, I heard what sound like digital chatter in my left channel while music was playing from my DAC into the amp.  I immediately turned off the amp’s power & noticed the speaker cable spades were touching.  After separating the spades, I turned it back on, but now there’s no sound on that channel.

Thinking I blew a fuse, I looked up internal photos of the amp online, but can’t locate a fuse anywhere inside the amp.  Does anyone know where the fuses are in this amp?
