danielbb Posted August 31, 2006 Report Share Posted August 31, 2006 Hi how do identify the resistor i need here.been searching for r260 or r280 resistor with no luck lolCheers Quote Link to comment Share on other sites More sharing options...
danielbb Posted August 31, 2006 Author Report Share Posted August 31, 2006 260red blue black26ohmz?lol i dunno Quote Link to comment Share on other sites More sharing options...
danielbb Posted August 31, 2006 Author Report Share Posted August 31, 2006 i have an identical amp, i think ill just open it up and get the same Quote Link to comment Share on other sites More sharing options...
audioguru Posted August 31, 2006 Report Share Posted August 31, 2006 You need to fix the problem that caused the resistor to burn. Or the replacement resistor will also burn. Quote Link to comment Share on other sites More sharing options...
danielbb Posted August 31, 2006 Author Report Share Posted August 31, 2006 incorrectly connecting speakers i think caused it, well the lady on the phone said that. It is identical to one in my other amp. Its the number r260 the correct way to identify it? I cant seem to find info to buy some Quote Link to comment Share on other sites More sharing options...
audioguru Posted August 31, 2006 Report Share Posted August 31, 2006 The resistor's value isn't r260. It is the 260th resistor on the schematic. Look at the other resistors, r258 isn't 258 ohms and r259 isn't 259 ohms.Look at the color bands on the r260 resistor on the good amp and get a replacement resistor the same.

danielbb Posted September 1, 2006 Author Report Share Posted September 1, 2006 I knew the number wasn't a ohm valve lol. i saw some key with numbers and colours to come to 26ohm. I though it was apart number or value, thanks for the info and help Quote Link to comment Share on other sites More sharing options...
danielbb Posted September 1, 2006 Author Report Share Posted September 1, 2006 Gonna check the colours on other amp. Its a cambridge audio A500, i have contacted them just to see what they say anywayCheers for the info :D Quote Link to comment Share on other sites More sharing options...
audioguru Posted September 1, 2006 Report Share Posted September 1, 2006 You say that you have another amp the same.It is easy to troubleshoot a stereo amp if only one channel has a problem, because the other channel is the same and it works. The defective amp can have its voltages measured and compared to the good amp. Parts can be seen with their color bands indicating resistances.

danielbb Posted September 1, 2006 Author Report Share Posted September 1, 2006 Is the resistor to the right ok? has burn mark from the other overheating Quote Link to comment Share on other sites More sharing options...
danielbb Posted September 2, 2006 Author Report Share Posted September 2, 2006 Is it 27 or 70 ohms Quote Link to comment Share on other sites More sharing options...
audioguru Posted September 2, 2006 Report Share Posted September 2, 2006 Yes, R260 is 270 ohms, 1% tolerance. Quote Link to comment Share on other sites More sharing options...

audioguru Posted September 2, 2006 Report Share Posted September 2, 2006 Is the Maplin one the correct physical size?Replace the other one too if you are worried about it. Quote Link to comment Share on other sites More sharing options...
danielbb Posted September 2, 2006 Author Report Share Posted September 2, 2006 yep its the right physical size, just reading up on how exactly they work to see if i need to change the other :) Quote Link to comment Share on other sites More sharing options...
