Resistor question

Depends on the application.

Also, depends on the tolerance....

If original tolerance is 7.5 +/- 10% and if the 82 ohm one measures at 82 ohms
then it is within spec for the original application of the 7.5 +/- 10%.

Also note some applications care about inductance (in wire wound resistors) vs non inductance. If non inductance is required it will usually be specified on the parts list and/or schematic.

It would be replacing a 75 ohm 2 watt in the -5v section of a Stern PS-1100 power supply.

in a power supply depending on where it is and what the tolerance rating is you could possibly decrease the -5 range. i have the stern 1200 and 1100 axial cap kits and i am currently working on the rebuild kits for them as soon as i finish the midways p/s kits i am doing.
 
Yeah you should be able to sub the 75 for 82. It might run a tad hotter but I think it will be okay.

Its just a current limiting resistor before the 7905.
