This is a repo for all things TekTronics regarding the TDS30xyz series oscilloscopes like the TDS3012B
I started a thread on EEVBlog and this repo is a compliation of that page: https://www.eevblog.com/forum/repair/tektronix-tds3012b-repair-help-needed/ and several others from around the internet, and useful tools that may help others to fix, maintain and enhance their scopes.
