Simply power it ON. I don't think there are components will fail over time.

???Pre Amp Service???
Howdy..I have a 20+ y/o,Class A Pre Amp that has been sitting in a box for almost 3 years now..I bought it as a matched pair with power amplifier just to use the amp,so never even powered it up to check it out..Last night I unboxed & set it up to check it out for possible listing to sell..Everything works fine & it sounds simply beautiful..
My question is,are there components that wear out with age like the capacitors of a power amp that it would be a good idea to replace before selling to insure proper function in the future?
Thanks much,take care...
