Item No.: #5A201 This is a part removed from a Yamaha SA-60 manufactured in the 1970s. Considering the business aspect, parts were likely standardized as much as possible. Therefore, it's believed to be a common part with other models. Based on my review of catalogs, it appears to be shared with the following models manufactured around the same time (and may also have been used in other models manufactured around the same period): AE12 SA60 The item has been cleaned and polished with polishing agents before listing, but it's not completely free of dirt. There are no screws that are stuck and cannot be turned, but as it is an old used item, some screws may be difficult to turn. Please be careful when turning screws during adjustments.
