Well as I recall the mag tuning switch is 2 switches. Do they both work?

The AF tone is just something for you to hear. It is the modulation on an rf signal that you are injecting. Most people "tune" by listening to the volume of the tone, but NO tone is necessary you could use a volt meter.

This adjustment seems to be to center the magnetic tuning. The change in audio level is not great, nor is it very sharp. I recall hunting for it.
