[NJARC] Resistor question.

[Goulart, Stephen F (Steve), ALABS]

Dave,
The nearest standard value is 12K. The standard values ranges are used
in most electronics design in that what ever exact value the designer
got in his calculations the nearest standard value is used. Mostly this
is okay with 10 % resistors and is why many old radios work fine with
resistors which are off value. 

The exceptions are where the value is critical meter multipliers, etc.
This can include some networks for audio frequency generators and tone
controls.

Hi dave,

	Plus or minus 10 % for ohms should not be a problem. You can
always go higher in wattage , never lower. Space is the only problem
with higher wattage.

Hi all,
 
I want to thank Nick and Steve for helping me at the repair clinic, it
was  
my 1st time attending thanks again. Here my is question: If I need to
replace 
a resistor what is the rule of thumb? Choose exact wattage and ohms? Or
is 
there room, +/- either way. If I was replacing a 1/2 watt 13,000 ohm
resistor 
what would you choose?
 
Thanks, Dave LeMay
