Panasonic SA-70 Vintage Wooden Case Receiver

Rare Panasonic vintage receiver, haven’t found any others online. Tested both the main and remote speaker inputs and both behaved the same way with the left speaker at normal volume and the right speaker quiet and only able to be heard when balance is to the right. Tested with am and fm radio. Sound quality tended to be somewhat crackly but may have been due to poor signal as I was not using an external antenna. Several of the selection knobs in front are missing but still usable. One of the screws for the speaker inputs is missing but you can still use either the main or remote speakers just fine and it can likely be replaced by a screw of the same size. Wood is chipped on one side as can be seen in photos and there is some fading, scratches and marks on the top and some rusting on front but overall not bad for such a vintage machine.
