that1crzywhtguy Posted April 22 Share Posted April 22 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!

that1crzywhtguy Posted April 23 Share Posted April 23 Cool I'll get on that. Anybody make a full list of cap values? The sub came back to life after some time and is working fine currently. When it went out I was really pushing it to see what It could do. Is it recommended to replace the resistor too even if it's not currently damaged? I'd be tempted to raise the watt rating on it, but would that pose a risk to other components? Thanks for the advice! -Sterling Quote Link to comment Share on other sites More sharing options...

sanscorp Posted April 23 Share Posted April 23 I am also attempting to repair a 115SW and replaced all of the electrolitic capacitors. I have power (led is on) but no sound at all. I also replaced the large (burned) resistor and the 31C fet. I have an oscilloscope but just now and Inhave no idea where to start and how to safely measure on the amp board (not PSU). I have not been able to completely remove the glue.. specially under the two TL047 quad amps. Any hints on the removal of glue too? My hot air just died on me so I'll have to wait anyway. Thank you in advance! Quote Link to comment Share on other sites More sharing options...
