PLEASE HELP ME. NEED ADVICE

Hi I would try the cheater plug which you can get from a Dollar Store 2 for $1. If that does not work I would tighten down the transformers on the chassis and place some
neat dampening blocks under it. Check your polarity to make sure it's correct. Some people will reverse the wall plug and get great results. Some people have problems with Line Conditioners too. Take it out of the loop. Sometimes your tubes may be weak and need replacing or rebiasing. Just some thoughts! Also check the tubes in the preamp. With the cover off and the volume cracked open
tap the tubes with a pencil eraser. If you hear noise coming through your speakers turn off everything and unplug the gear and clean the tube pens with an exacto knife then isopropyl alcohol and treat it with some Pro Gold, etc. If one those don't help hmmmmmm!!!!

Please see the following excellent reference:

As you'll see, interconnect cables are usually key factors in how hum/buzz is introduced into a system. They should be kept as short as possible, and should be chosen to provide low shield resistance (although unfortunately that is often not specified, and trial and error among different cables may be the only way to tell).

I had a constant buzz through my system when inputing the cable box...... Satellite box never made a buzz but the cable box created a loop..... now I keep video and music separated...... 2 ch. is only music...... No more buzz of any kind.....

I don`t care what you do to it the CJ MF2500A is always going to hums.It was made that way.I sent the one I had back CJ and they said nothing could be done about it.SORRY

Thanks guys for your input.
By the way, what is a cheater plug? What does it look like?
Also, any suggestions on what integrateds might be really "quiet"?
Both my cj amp and pre were solid state.
I have Kef 205 reference and only do redbooks cds.
Any suggestions would be appreciated.
Thanks,
