SONY TC-K670 service manual

Hello all HiFi fans!
I'm looking for the above mentioned manual. Owning a TC-K670 since 1992, which is out of order after 7 years of service, I'd like to repair it.
Here I also want to thank Hi-Fi Engine for downloading a manual of a similar SONY deck, the TC-K870ES. It perhaps helps me too.
