Fixing a tiny Tektronic oscillosope
I have a broken Tektronix 221 oscilloscope, while not directly useful anymore it is an amazing looking scope, so let's repair it. This scope just has a single channel that can measure up to 5Mhz, but it looks so cute :D A lot more info about this and other Tek scopes can be found on the amazing tek wiki: https://w140.com/tekwiki/wiki/221 Let me know what you think about this repair, and consider buying me a coffee: https://ko-fi.com/riktw
