TU-666 Schematic - Finally

Finally was able to get a TU-666 schematic for my tuner.
Thanks to Klaus Mollgaard and HiFi Engine site.
Now, I hopefully can repair my AM band which was knocked out by our cat who thought he should 'mark' his territory, all over my beloved round green dial tuner.
If I can't sort it out, at least I can provide all the docs to an expert tech to hopefully get my tuner back to 100%.

I had purchased a download manual recently, but without the schematic.

Thanks guys, great site.

PS: I've also found a few other manuals for other vintage gear I have on this site.

TU-555 schematic

So I would also very much like to thank HiFi Engine for the valuable work that this site does for us vintage/junk collectors!
I just downloaded the schematic & service manual for the TU-666 tuner, but what I REALLY wanted was the info for a TU-555 tuner instead, which I can't seem to find (on any "free" sites, anyways..).
I hope that the circuitry is much the same for the 666 as 555, they are certainly from the same series & vintage. If anyone can help with this, it would be appreciated.
