【Condition of the product】
- About SG-3880BL modified (Serial numbers are 23018 and 23019)
- Currently, GOTO UNIT has discontinued the production of beryllium specification units, but this product has a beryllium diaphragm incorporated into the 3880 series magnetic circuit by us, hence the "modification" label on the nameplate. Therefore, it is in almost new condition.
- The product has been taken out of the wooden box for photo shooting.
- To fully utilize the performance of this product, it is recommended to age it sufficiently before use.
- The stand in the images is included.
- Due to the weight of SG-3880BL modification, it may be shipped in two separate packages. Please consider this.
