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 !!!
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.
