Sony TC-K60 repair

Today we are repairing Sony TC-K60 cassette deck from late 1970 !

I purchased this cassette deck for a price of cappuccino with a muffin. And it was clearly broken. But I decide to tinker with it and make sure it works !

I think this Sony TC-K60 cassette deck is pretty decent example of late 70 cassette players / recorders and was warth my time and efforts to restore it.
