Parts from my working SB-303 that has served me well for almost 15 years using it every week with my SB-401/SB-200 station. I only had to make a few minor repairs through all the years. Still working when parted out. I acquired a near mint SB-303 as a replacement. All parts sold as is. Clean and deoxit as necessary before using. Sold for parts or not working due to the age of the unit. Please understand, this is a project piece of equipment and no warranty is expressed or implied. It is sold for you to restore or use for parts. There could be other issues with the unit that are yet to be discovered. Will require maintenance sooner or later.
