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

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
I have to say my unmodded 555 (mk 1) sounded pretty good compared to my modded DNA-1. Mr. Pass really knows how to make 'em.
