Fostex X-18H, a model with double-speed recording. Therefore, tapes recorded on other devices will play back at double speed. Operation confirmed. Rubber belts replaced with new ones. Each part cleaned. The unfortunate point is that the counter reset switch is missing. However, you can reset it by inserting a pen or similar object into the hole and pressing. AC adapter is not included. A 12V 900mA center-positive adapter is the original, so aftermarket ones will work if they match these specifications. There are more scratches and dirt than you can see in the photos, but it works properly. Batteries are also possible.
