Four unused 2SC372 transistors from Toshiba, a staple of electronic hobbyists in the 1970s and 1980s. The grade is -O. These are the distinctive "silk hat" package type, not the later TO-92 package. This is a set of four with matching lot numbers. The image is a representative photo. Multiple sets are available, so the lot number may differ from the image. #DIY #ElectronicHobbyist #ElectronicComponents #Transistor #2SC372 #ShowaRetro
