If you order a set of these, please consider buying me a coffee This is a SMD component spin of Simon.Plata’s design on Atari age forums. the thread with all the design info is here http://atariage.com/forums/topic/271678-simple-diy-composite-video-mod/ this spin uses 2x SOT-23 for the transistors and replaces the board previously made at https://oshpark.com/shared_projects/BsstvIeq Q1 and Q2 can be MMBT3904/3906 as per Simon’s original design but I have BC850/859 on hand so I’ll be trying those out as they are nominally similar so the silkscreen just indicates where the NPN and PNP variants go but in theory any similar general purpose transistor pair should work. C1 is optional and does not appear on the original design but some people have found it beneficial to put a cap on. check the linked thread for details
