Looking For Sony IC

[KenwoodM2A]

Hello Folks,

I attached a photo of an old and probably obsolete chip from a cassette deck of mine.
The description in the service manual identifies it as a " Mechanism Driver" and a part number of
KC-821 which I believe to be nothing more than the Kenwood part number.
I have tried searching for the part number as well as the number on the chip but yet can't seem to find any reference to that number. I'm sure that there must be some NOS chips out there still kicking around but not having any luck locating. Although I do have a couple spares of this chip, I would like to locate another one to replace the defective one that I changed.
Anybody know how to locate these things?

Thanks!

Roland

That is a hybrid, not an IC
Much harder to find any information unless you can find a service manual showing the internal circuit
