| Is it ok to use 5% 0.1 ohm output resistors? |

Depends on what?:confused:
I will be making an amp by bootstrapping an LM3886, and adding an output stage. I'm not yet sure how many transistors I will use in parallel, but it probably will no less than 4 per rail.
How does the accuracy thing work? If a resistor is 0.1 ohm 5%, then do I multiply 0.1 times 5% to get how much the value will vary? So this resistor's value would be between 0.095 and 0.105 ohms? Or is it 5% of something else? |

Correct. |

Depends on the application of course.
If the voltage difference is not ok when you calculate with maximum and minimum possible values in the +/- 5% range, get a whole bunch and do some comparing and matching.
If you have cheap/free output transistors, try it and see if anything blows up. Use a cover though! |
