So the guy that gave me a set of vintage cerwin vegas also gave me this Kenwood KR-7600. He said its hardly been used, was never abused and has been in storage for 30 years.

Anything I should know before plugging it in and running it? I saw DC offsett mentioned somewhere in relation to kenwood stuff....Dont want to damage anything here, as I may be replacing the pioneer SX-727 I have with the kenwood, mainly because of the 80wpc instead of the pioneers 35ish

Thoughts?
Manuals?
talk to me people! :D

Now for the pics

If it's been in storage for 30 years, it's going to sound pretty funky at first. Don't connect speakers to it until you check DC offset.
There's a free owners manual at hifiengine.com.
 
Make sure any mute buttons if present are off so you don't get blasted later.

I would power it up raising volume slowly just to see what problems may be present or not.

Anything in storage that long may have volume and balance static or weak channels and will probably need a deoxit/faderlube cleaning.

Here's a deoxit checklist:

At some point I would clean up the interior of all that dust (I use 99.9% anhydrous alcohol for electronics cleaning. Swabbing with q-tips or cut t-shirt squares for large areas but there are also special circuit board cleaners) and of course let dry thoroughly before powering up after any application of liquids or sprays. I would avoid cleaning those metal blocks or metal or plastic trimmers with slotted or + or hex screw heads or until you know what they do since they can affect adjustments.

There's also a special tuner cleaning thread here:

But I would see if you have problems first.
The problem may be more alignment or antenna related than dirty tuner.
