I enjoyed that amp in the 90's! It's well worth keeping (even though I didn't....). Yes, replace the electrolytic capacitors after 20+ years in any amp. I did that with a tube amp and it was a very nice improvement.
If you are handy with a soldering iron, you can do it yourself for low dollars (actually, you don't have to be that handy, because I was able to do it - - just get a good Weller variable control solder station and a good solder sucker, and you can tackle anything). There are many great Panasonic electrolytics that are readily available from Mouser or Digikey, and they are rated for higher temps.
You will hear a bit of "sonic restoration", I'm guessing.
