Telefunken Gavotte 55 restoration part 5. Getting rid of the hum, and getting FM back.
The issue of excessive 50Hz hum was not completely resolved in the last video in this series on the Gavotte 55. I was actually at a loss, having thought of all sorts of reasons for its existence, heater supply interference being the primary one. However, it was not the source. It was actually ... no, watch the video :) The non-existent FM was also awaiting due attention. Here the reason was a lot simpler. Enjoy the video.
