I am not familiar with the Macbeth but I have found spring reverbs to 
be, in general, sensitive to interference.

If it is possible, try changing the position of the tank or unit. 
Sometimes its angle relative to something else has a strong effect.

On my Doepfer spring reverb, I spent a lot of time moving the tank 
around on this lunchbox trautonium thing I slapped together.

The tank did not like sitting too close to a midi/cv module and became 
quieter mounted perpendicular to the backplane.

This worked for me; hope it helps you.
