Could be the same magnetostriction effect that happens with a H/K Cit. 2.
In addition to the mechanical damping other posters have suggested, turn on surge control seems to be in order. I'm assuming vacuum rectified B+, Therefore, put a NTC inrush current limiting thermistor on the primary side of the power trafo. Select between a CL-90 and a CL-130, depending on the amount of current being passed.
