Which components should be replaced when servicing a power amp?

[Cameron]

I'm servicing my NAP 110. Apart from capacitors, are there any other components worth replacing because they may have aged (output resistors, voltage regulators, bridge rectifier...)?

Electrolytic AND tantalum capacitors are the only bits needing replacement.
Double check for any sign of overheating of all the resistors and if there is no brownish color, leave them alone.
A bit of Deoxit on connectors, thermal paste if the old one is completely dry and you’re good to go.
