Just want to check to ensure a resitor of "X" value and "X" wattage can be replaced (upgraded) by a resitor of the same value and tolerance with a higher wattage in a signal/power audio curcuit. Wanting to replace some 1/2 and 1 watt carbon resitors with film type, but can only find some of them (MILS) at 5 watt. Thanks.

No problem electrically going with higher wattage rating (or tighter tolerance). Would likely be physically bigger though for the higher wattage. I've had to ream out the holes on the PC board because the leads were bigger.

Thanks Bill, One more question: I have a 60.4 ohm resitor I want to replace: the closest I can find is 62 ohms. Any problem? Same with a 7.87K resistor I want to replace; closest I can find is 7.5 K or 8.2 K. Any suggestions or insight you can provide is appreciated.

Yikes, those are non-standard values!!! Is this what you measured the actual values, or is this what the schematic calls for?

Typical resistor tolerances are plus/minus 10% for common carbon, metals are 5%, precision 1%...you could buy several 62 ohms or 7.5K and just cherry-pick ones that are closest to nominal...as long as you have a decent meter to measure them with.
