Up for sale is a Sony KV-5100 with battery pack and AC cable. The set was built in 1979 and is in absolutely in beautiful condition. I would rate it at 8 out of 10. Clean screen, straight antenna, and minor case scratches. It even comes with the OE UHF antenna and power cable. I replaced the batteries in the pack with new lead-acid batteries. The pictures of the set show it running on the batteries. Charge time is approximately 12 hrs. This is something you should do every couple of months to keep the batteries in good shape. This is one of the nicer pieces in my collection that I, unfortunately, have to sell off. My wife has come down with Cancer and the bills are starting to mount-up. You will be seeing me a lot more over the coming months selling off my collection. Help a fellow out here guys! Insurance only pays just so much. Our incomes come only from Social Security Disability. This baby is heavy, but will be well packed in a new box with plenty of packing material......Thanks for looking.
