Tearing down and replacing the tube in a TS-1 Mark 2 Microphone

I had to replace the tube in my TS-1 Mark 2 microphone. This is the teardown and replacement process.
NOTE: This video has some quality issues, including some blur, the audio has issues, and at some points framing problems. It is an experiment in using my GoPro for up close video recording, and while I learned quite a lot in this process, there's clearly some issues with the video.
I'm using it as part of learning how best to operate my camera equipment in order to make better videos going forward, as I have plans to make more electronics-related videos.
