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 believe you would be best served having a tech power these up on a variac. At least this is recommended with tube equipment that has been unused for a long period of time.
I would also recommend having the tech give the amp a good go through. I think you will be pleased with the performance of the GFA555II. A nice amp for the money.
That's good to know that SS equipment that has been sitting doesn't have to go through the same steps as tube equipment.
       Enjoy that amp and pre! What speakers are you running?
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)
