In Reply to: Removing toroidal transformer bolts posted by Russtafarian on June 29, 2004 at 12:38:55:
You can get a Deflex rubber circle to place between your transformer and cabinet metal from partsconneXion. Also, see if the bolt gets warm during operation. If so, get a replacement bolt made of stainless steel, that won't absorb energy from the toroid's magnetic field.If your transformer has an audible hum from time to time, your AC has distortion to the sine wave that includes some DC. The distortion is coming from another appliance in your house or in a neighbor's house that shares the same power step-down utility transformer. If it hums all the time, have your line voltage checked, as it may be excessive.
A direct mechanical support beneath the transformer as you describe is the only way to keep the cabinet metal supporting the heavy transformer from bouncing up and down (visualize a Sumo wrestler sitting on a trampoline during an earthquake) from acoustic stimulation. I found this mode was limiting the deep bass response of my InnerSound ESL-300 amp, and provided a solid butcher-block wood support for the whole amp, with stock feet removed and a layer of Deflex rubber in between, to cure the problem.
If you remove the bolt, you will allow the transformer to chatter on the metal and make things worse. You will also open yourself to possible amp failure and risk of fire!
