[Crist Rigotti]

I completed my restoration of this console radio and I noticed that the 3 position Tone Control doesn't seem quite right.  In the "first" position after you turn on the radio the tone is lets say bright.  Then in the second position, there isn't any change in the tone.  Then in the third position, there is a marked difference with the tone being lower and a lot less "noisy".  Is this normal?  It seems there should be a difference between all 3 positions. Tone control is #39 in the attached schematics.
Schematics are attached.
