That is a nice little integrated amp. I still have one somewhere here, although it hasn't been out in years. It was the first "vintage" piece I restored. The last time around with it, I "borrowed" the current topology from Poindexter's Musical Machine of Audio Tropic fame. Those 7408 outputs are tough, sound good and last a long, long time so be sure they are worn out (probably not) before you look to replace them.
The mods Eli suggested will get the front end into the millennium and help greatly. A replacement of the electrolytics is a must. A sprinkling of modern coupling caps will help. I cannot recall if this had a Sprauge Atom in there somewhere but I did notice they have a pleasant influence on the sound. They are still available.
