Nice score, those are good looking amps.
You should look at the DC offset to see if it's in spec.
Here's what I believe is the JP version of your 701:

Nice amp, they always have the problem with the switches, they break easy! I own the KA-801.

Enjoy it!!!

I have the KA-501 and KA-701. Great units but horrible switch design. Tought to find them intact these days. I was able to adapt a power switch from an older model to repair the broken switch on my KA-701. Here are the before and after pics.

Carl, nice amp. I think it's just about the cleanest and best looking of the (affordable) vintage Kenwood gear. Definitely check the DC offset and bias levels, and carefully adjust accordingly.

Enjoy!

got the dc offset zero'd out...
but the bias are a little high based on the service says. rec is 26mv mine is at 74.
