I don't have a 300 now to check, but I can't believe that on max, the spring is "Locked" down. If it were, it couldn't function as a spring.>>>>>
It is not acting as a spring. Think of it as being disabled. You are setting the VTF with the counterweight only.

Perhaps the resonant frequency is changed and if it is, it would change for the higher which is not good at all. Setting it to zero, gets it out of the system as I remember.

For optimum performance on the RB 300-600--900-1000 set the dial pass 3 (this locks the spring down to prevent vibrations down the arm tube) then set tracking force with gage.
