rodspc Posted November 7, 2004 Share Posted November 7, 2004 if anyone can give me the info for the r12 resistor that is on the BASH board i would appreciate it need value and wattage Quote Link to comment Share on other sites More sharing options...
craftsman Posted November 7, 2004 Share Posted November 7, 2004 For the record, The value of R12 resistor is 680 OHMs. I was able to measure mine and replace it before it become a piece of black carbon. As for the wattage, according to it's physical size, it looked like a 1W unit and that's what I replaced it with. However, thinking back, I should have replaced it with a 2W unit to provide a bit of safety.... Another resistor that usually gets burnt (mine did) is R26 (located above R12). Once again, I measured it and replaced it before it became a piece of black carbon. The value of R26 is 56K. Once again I replaced it with a 1W unit according to it's physical size. I should have held out for a 2W unit. All of the resistors I used were 2%. Richard Quote Link to comment Share on other sites More sharing options...

007 Posted November 7, 2004 Share Posted November 7, 2004 so the color code should be blue, gray, brown, red Quote Link to comment Share on other sites More sharing options...
rodspc Posted November 7, 2004 Author Share Posted November 7, 2004 blue gray brown red ? red can't be the last color how about gold or silver which is gold=5% and silver=10% Quote Link to comment Share on other sites More sharing options...
rodspc Posted November 8, 2004 Author Share Posted November 8, 2004 r26 what's the value of that one ? damn nevermind i see it now Quote Link to comment Share on other sites More sharing options...
craftsman Posted November 8, 2004 Share Posted November 8, 2004 I also mounted the resistors about a 1/2 to 3/4 of an inch above the board - just to give it a bit more air.... Quote Link to comment Share on other sites More sharing options...
rodspc Posted November 8, 2004 Author Share Posted November 8, 2004 i ordered 5 of each last nite 680 ohm and 56k should be here this week Quote Link to comment Share on other sites More sharing options...
craftsman Posted November 9, 2004 Share Posted November 9, 2004 You mean 56K right? Quote Link to comment Share on other sites More sharing options...

craftsman Posted November 12, 2004 Share Posted November 12, 2004 I'm either getting too old to remember or I can't be bothered to remember. I just purchased a packaged one with the value written on the package ! Quote Link to comment Share on other sites More sharing options...
rodspc Posted November 12, 2004 Author Share Posted November 12, 2004 there is either gold,silver ,or none gold 5% silver 10% none= 0 Quote Link to comment Share on other sites More sharing options...

rodspc Posted November 23, 2004 Author Share Posted November 23, 2004 haven't had a chance to mess with them yet been busy but will do it in the next week or so i hope Quote Link to comment Share on other sites More sharing options...
craftsman Posted November 23, 2004 Share Posted November 23, 2004 No problem. I was just afraid that something went "boom"... Quote Link to comment Share on other sites More sharing options...
blacksheep Posted December 8, 2004 Share Posted December 8, 2004 Sounds like My R26 is fried as well, gang! I cannot get any reading on it with the multimeter while the R16 read 658..shouldnt it be 680? Is it going out as well? Any advise for me? Thanks!

craftsman Posted December 8, 2004 Share Posted December 8, 2004 It does look a little worn out. Just replace it. R26 is 56K - I believe that it is a 1 Watt resistor but judging from the heat, you should replace it with a 2 Watt one just in case. As for R12, don't worry about if it is off by a couple of ohms - that's what suppose to happen. However, if it looks discoloured like the other one, you should just replace it at the same time.

williamkusumo Posted January 6, 2006 Share Posted January 6, 2006 I have the same problem with my Promedia 4.1. Plugged it out, plugged it back in and nothing. But what I notice on mine is if I wait for 3-4 days, and then plug it in again, it would magically turn on again! I tried checking the inner circuit, the resistors and capacitors on the board do not have any charring/blemish. Fuse is also fine. Does any electrical engineer in this forum know why this is happening? Let's say if a resistor did blew, is it possible for it to "heal" itself after a certain period of time?! Or maybe this has something to do w/ transformer discharging leftover magnetism? (sorry, just thinking out loud, I deal w/ software, not hardware ) Thanks in advanced!

jgr82 Posted January 15, 2006 Share Posted January 15, 2006 Hi, I am the person that posted "Sub making Rumbling Noise" on 1-13. I read your reply here and that caused me to open up my sub. I found the R-12 and R-26 you mentioned. My R-12 has a brownish coloring around it on the board and the coating on the R-26 is all cracking and flaking off. So do you think that perhaps this is what is causing my Sub to make these intermittant rumbling noises? Did you have the same problem and did these replacements fix it? I notice that usually when I first turn on the speakers its fine for a while then it warms up and the noises start. Even with the computer off the sub will make these rumblin noises. I think I can easily remove and replace the resistors if I can find the replacements. I emailed Klipsch to see if they can send them to me. Thanks for any input, I greatly appreciate it.
