Hi Everyone,
I'm attempting to troubleshoot my Definitive Technology Supercube III and proceed with component level repair if possible. I have not been able to find a DIY guide on this.
I've confirmed the amp receives power indicated by the Red LED light, however I have no sound/bass coming from the amp when I attempt to unplug and plug the RCA sub cable to the LFE input (the photo I took is testing other inputs). I have a secondary sub, which I tested to eliminate that it's an sub output receiver problem.
The board looks fairly clean except for ST tip32c and LM337LZ transistors that seems to have some brown residue around the yellow potting material (photos attached below). I have not tested the pins for voltage and wasn't sure if this would affect the LFE input for sound.

Does anyone have a schematic or way to possibly confirm the voltages on the transistor.
Thanks,
