Help Preamp Hum


I am an owner of a Golden Theater GTX 1 preamp/processor. I have owned this unit for approximately a year and have really enjoyed it. Recently, I noticed an annoying buzz/hum emitting directly from the unit. I can hear the buzz/hum from a few feet away. It isn't noticable when I am playing music or watching a movie and hasn't had a negative effect on the preamps performance; however, it is annoying the shit out of me (excuse my language). I diconnected all components from the preamp, took it out of my rack, and brought it to another room in my house to see if I could duplicate the hum/buzz. After plugging the unit in another outlet, I still noticed this annoying sound. Unfortunately for me, Solo electronice, the manufacturer, went belly up half a year ago and the warranty is useless. The noise appears to be mechanical in nature and may be the transformer. I am asking for your assistance. What are your thoughts and does anyone know of a reputable repair shop in Orlando, FL or one that would allow me to ship the amp to them in the mail? Thanks in advance for your assistance.

Why don't you take off the cover and make sure that the screws holding the transformer down are tight. Of course, please make sure that you first unplug the unit. This is just a suggestion...I take no responsibility for any shocking experiences !!!
I did take the cover off to see if that was the problem. Vibration does not appear to be the cause of this sound. There are no screws holding the transformer down. It is soldered to the board and held securely with a strap. It isn't the type of transformer you would find in an amp. I did put the amp on after taking the cover off and the hum/buzz does seem to be coming from the transformer. Any other suggestions?
You could try to put a VPI brick on top of it. That's what they were made for but it's not going to be your long term solution for your particular case. It sounded like a faulty transfomer more then power circutry issue.
I had this happen once and I couldnt get rid of it. Come to find out it was contaminated power from a neighboring apartment. Try plugging it in elsewhere and see if the problem continues. There are also several other threads on this problem. A search may get you the answer you need.
