Hi there! I just picked up a r-115sw free locally. It worked great for about 15 minutes when I tested it at home, then poof. No sound at all now.
I found this thread and then poked around, seeking a dead resistor (started with r39). I don't see anything visually wrong at all, and r39 tested appropriately on my multimeter.
Any other ideas of good places to start checking? I'd love to get this thing working! It would be replacing an energy 8" XL sub—a big difference.
Thanks in advance!
