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

I have the same combo except mine is the earlier 555. You'll be very impressed with the 565, especially if you use a turntable.  I had mine sitting in the storage for 6 years and and plugged them right back in with no issues. I also have a Pioneer receiver SX-980 that sat in storage for almost 12 years and lent it to a friend and we plugged it in and he's been using it with no issues. Having a tech check them out is always a good idea if you want to be real safe. Nice find....
rocray, just starting to build and the only speakers I have worth mentioning are a pair of Dahlquist dq 10’s. Am trying to find some Infinity cs3009 but not having any luck. I am trying to avoid spending a bunch of money so I am just piecing things together that I have found. I also have a Yamaha M2 amp, and a B&K st 202 and preamp. I am running a older Yamaha powered sub but can’t seem to make it blend. 
Sounds like a nice set up! For the longest time I had the same issue with subs. They filled in the lower regions ok,but they always sounded like something wasn't quite right. I finally connected them directly to my amp using high level inputs,and SHAZZAM!  They now blend very well. (At least to my ears)
