If the Kenwood is the KR-8840 QUAD, it is 40 watts per channel and was made between 1974 and 1978. It retailed for 800 dollars.
Your Akai cass player, GXC-570D was made between 1976 and 1978, it retailed for 900 dollars.
I could not find info on the Sony, I am using a Orion Blue Book back from 1991. You may want to find someone with a newer copy.
