Buzzzzzing Transformers

Thank you all for the thoughtful and very informative answers. I am currious, and maybe I should be posting a new thread for the following: I recall having read some years ago about a tweak that a reviewer of "positive feedback" performed on his amp's toroidal transformers. He removed the top holding plates and the screws that hold them to the chassis and just let the tranformers stand in place without any fasteners. He reported that the music was sort of liberated and that detail and inner resolution etc, etc, increased dramatically. Of course he warned that the transformers were loose now and any attempt to move the amps should be done very carefully! or disaster could ensue.
How do you like that?

Gs5556, You guessed it right, my transformers are toroidal. Their maker is obscure and out of business now, so I did not mention the name. They are "Acoustic- Electronics" "photons" One currious modification, that I think was added later by their first owner, was that they have a second smaller toroidal transformer sitting on top of the main one. I think this gave additional power to the amps.

Tphalieros, the "loose transformer" tweak makes sense. The 60HZ vibration from the transformer was decoupled from the PC boards etc. in the amp and removed a colouration. A rubber mount system would probably have a similar but safer effect. You see this in some amps (YBA being one) or a separate box entirely for the power supply.

Go to psaudio.com as they have a section on transformer buz! very interesting article! Happy Listening!

T,
Your amps were originally made by some nice guys in New Jersey. The originator was Roger Paul. He has a new company that makes a preamp that I think is called Hcat. He has a website that I can't remember. He probably could give you some advice. The Photon was a great amp.
