Hello @ngen33r! Thank you for sharing so much great information about these repairs. My R-115SW started intermittently cutting out more and more frequently, so I watched several of your repair videos and prepared to order a new resister and caps from DigiKey for a full recap. Imagine my surprise when I opened up the sub and found that it already had a giant 10W resister from the factory! I don't see any evidence of overheating on the resister or any of the caps. Any suggestions on what could cause it to intermittently cut out (complete loss of volume) for a few seconds at a time and then go back to regular volume? The cut-outs seem to have gotten more and more frequent to the point that it is no longer usable. I have not observed any distortion or clipping or other symptoms.
My first choice would be to sent it to you for repair, but it looks like you must be backed up enough that you are not accepting repairs, so I'm hoping you can point me in the right direction to do it myself. (I do have electronics repair background and tools, so the desoldering and resoldering is no problem.)
Did replacing the caps fix your problem? My amp is now doing the exact same thing.
