This walkman uses two standard AA size batteries for power.
This is an used item, so it will have some marks and scratches that might not all be visible in the photos.
The difference in price in my listings for DD walkmen of the same model is based on color and cosmetic condition. I also take sound quality into consideration when pricing them too.
PLEASE NOTE: This item has been restored, so it is guaranteed to work properly. The fast forward and rewind on this model are noisy if the walkman is lying down flat so turn it on the side if the noise bothers you during rewinding of a tape.
Type of restoration done: Rubber drive tire which is slanted was replaced with a new slanted one which I make myself as they are not possible to find, after the replacements the speed was adjusted properly with Sony Professional test tape at 3000Hz. Center gear wheel: outer plastic ring which cracks on this model due to age, it was replaced with a brand new stamped one for smooth rotation, not of the type that uses bolts made of two pieces but a proper single piece stamped outer plastic ring was installed, so the job was done properly with a high quality ring installed. Mechanism was disassembled and checked during the repairs, and smaller steps taken as necessary to make sure it works properly.
ABOUT THE RESTORATION: Why is it important for the item to be restored? If you are buying vintage electronics that were NOT restored (no matter if used or brand new sitting in the box) and the sellers state were tested and work, you should know that they don't work as good as the day they left the factory without the need of any restoration work done. You should know that it is extremely rare( 1 in 10 or 20 chance) to see a vintage item working PERFECT after sitting for some 20+ years without the need of any restoration work done. This is because rubber gets old, plastics shrink and crack, electronic components that have liquid in them won't give the same performance as freshly made ones, etc. That is why it is important to buy an item that has been checked and restored. Repair places don't do restorations but just fault finding. They just find what electronic component is causing a device to malfunction and replace that component only. This is because it takes a lot of time to restore an item and unless you ask and are ready to pay, they won't do it.
