Kenwood TK-250 Amp

I recently picked up a Kenwood TK-250 which is supposedly an early solid state amp from the mid-late 60's. I can not find any info on it anywhere. Any here know of it or had any experience with it?
Colts1 - is listing the owners manual for the TK-250. I googled the amp just for fun and found several links.
Colts1 - ON further review it looks like I have passed on bad information. There is a Kenwood TK-250 radio product as well as your amp. The google links refer to the radio, not the amp. My apologies.
