Riparazione Oscilloscopio TEKTRONIX 2215A Commutatore e Taratura Verticale

In this video, we finish taking care of the 2215 A. I noticed that channel 1 had a lower amplitude than the reference and distorted the signal when I applied the calibrator to the input. Furthermore, the AC/GND/DC switch didn't work, always remaining in the AC position. I hope this helps, enjoy the video!
