Another nice video on the same subject,
this is from ENAC, this is Clarence Kane company, he is probably the oldest person in the world that does mic repair, he specializes in RCA ribbon mics for many years:
A truly heartwarming story, very well filmed. I also find it wonderful that his work and knowledge will find a continuation into the future. I am very impressed. Thanks for posting Whoops!
For my new passion, working with microphones, I have also learned something practical. The wooden microphone holder is a simple but effective solution against the constant turning away of the microphone when tinkering.
