leonovo Posted August 18, 2023 Share Posted August 18, 2023 (edited) Hello. I have a Klipsch model RSW-12 15 years. Yesterday I turned on the button, there was a bang. I checked the fuse, it turned out to be burned. I set a new one, turned on the button, and again the fuse burned out. I have little knowledge of radio engineering and tools. I ask for repair advice. Thank you. I have a scheme, but only for the model RSW-15. Edited August 18, 2023 by leonovo Quote Link to comment Share on other sites More sharing options...

leonovo Posted September 5, 2023 Author Share Posted September 5, 2023 Hello. I have a RSW-12 model. When turned on, the fuses began to burn. I disassembled - there is no visible damage. Maybe someone has a scheme? Or can someone help with advice? Quote Link to comment Share on other sites More sharing options...
babadono Posted September 5, 2023 Share Posted September 5, 2023 My understanding is the electronics for either rsw-12 or rsw-15 are identical. Quote Link to comment Share on other sites More sharing options...
babadono Posted September 5, 2023 Share Posted September 5, 2023 Where are you located? There is a servicer here in the U.S. that will re build your amp. You just ship the electronics. Edwards Electronics on EBay. Quote Link to comment Share on other sites More sharing options...

OO1 Posted September 9, 2023 Share Posted September 9, 2023 check the solder joints , make sure there are no cracks in the PCB or cold solder joints that need to be reflowed Quote Link to comment Share on other sites More sharing options...
leonovo Posted September 19, 2023 Author Share Posted September 19, 2023 I checked. Now the capacitor has exploded. Quote Link to comment Share on other sites More sharing options...
OO1 Posted September 21, 2023 Share Posted September 21, 2023 the 4 large capacitors are due for a recap , always wear eye protection Quote Link to comment Share on other sites More sharing options...
babadono Posted September 22, 2023 Share Posted September 22, 2023 My $0.02...if you are going to replace electrolytic caps get 105 degree replacements. A few bucks more, who cares your labor is worth much more. Quote Link to comment Share on other sites More sharing options...

avguytx Posted December 11, 2023 Share Posted December 11, 2023 Buy an external subwoofer with an amp maybe? Buy the new version sub and hope it lasts longer? Seems sub amps for years were built using some cheapo capacitors that had a short life span. I went through the same things with a Sunfire HRS-12 powered sub that I've owned since 2007. I've replaced the main filter caps and some smaller ones and it's worked fine for years now. But, it's doing something again and I will probably send it to a tech and have him go through it. Cheaper than buying something new that will most likely fail in a short time. Everything is built with planned obsolescence anymore. Especially in last 20 years. Manufacturers literally told us that back when I was a rep for home A/V and car audio companies from 2001 till 2009 when the market went to crap. I got out of it then.
