Adcom Gia 555ii amp and gfp 565 preamp


I recently purchased these in like new condition, the downside is that they have been in storage for about 14 years. Is there anything I should do before hooking them up and turning them on?                   Sorry, it is a gfa 555 ii amp

Inside climate controlled storage in boxes. There literally is not even any dust inside and I looked at the four main capacitors on the amp and they seem to be holding in there but there is no doubt in my mind they should probably be replaced on age alone at some point. Haven’t looked at the preamp yet.
Well, I fired them up and am not disappointed. I think that they sound great! The amp capacitors seem to still be storing power well and the units are spotless, in and out. I realize that it is lower end stuff comparatively, but I am happy with it. Thank you guys for your responses and advice. This is a cool site. 
At some point you may want to have Jim Williams mod the 555ii. He did my 555 a month ago and the difference was amazing. Deeper tighter bass and much better details in mids and highs. Www.audioupgrades.com
