Sony

From the tip shop, this was is filthy condition. Believe it or not it has been extensivly cleaned. 

These sound particularly good, if you allow for the fact they have very little bass response, compared to later "boom boxes".

Sony sold these for quite a period, and there was a "B" model from 1975. This one has the optional NiCad pack that would have died many years ago. I remember them being very expensive when new.

This unit works, but needs extensive work, and a belt kit, to return it to its former glory.
