Kenwood KA 8100 Int Amp Inquiry Re : restoring

I just purchased this unit and it works great however wondering if I should replace caps or use it as it is.
I am using it with ZU Omen Mark 2 speakers.
thank you
Your Kenwood Integrated is over 40 years old! I sold them around 1974-76. I would definitely have the amp recapped. By the way, the KA8100 was decent, but nothing special. I remember the sound getting very compressed and thin at higher volumes.  I wouldn't throw too much money into it.  I think it sold for $400-500.00 at most
