Thank you for shopping with Threads and Wires! I’m a small one-person operation that specializes in used and vintage electronics. If you have any questions, feel free to ask. I may not be able to answer immediately but I will respond as quickly as possible. This listing is for a Sony ST-S550ES tuner. This unit has been tested and is working with no known issues. There are some signs of wear so please see all pictures for details on condition. It includes RCA cables but no other accessories are included. You are guaranteed to receive the item as described in the listing. I do not do advanced electrical testing of the internals so I cannot guarantee that everything is up to the same specifications as they would be coming out of the factory. There is an understanding that as electronics age parts such as capacitors may fall out of factory specifications. There may be other issues with “as is” units that are not listed in the description. It is unfortunate that I have to write this, but scammers do exist.
