Turntable hum problem after demagnetizing

I borrowed a friend's Benz Aesthetix demagnetizer to try out. (Oracle Delphi V, Wilson Benesch ACT 0.5, Benz LP-S, Cardas Golden Cross phono cable, Pass Labs XONO phono preamp). After using it, I now have a huge hum that wasn't there before. There also is static if I clean a record with my carbon fiber brush or touch it to the stylus. Also when I touch the tonearm the hum increases. What is going on??? Any help would be appreciated.

I'm going with the odds of a bad connection such as a wire that came off, or broke off somewhere.

thanks for the comments so far. All connections are good. Both channels play. I'll try disconnecting the cartridge tomorrow and see what happens. I did follow instructions exactly as specified. Also, this is a Benz made demagnetizer and I'm using a Benz cartridge - seems strange that they wouldn't be compatible.

One thing I just thought about is if the unit was exposed to a cold temperature, maybe moisture condensation formed inside it, shorted it, and passed enough voltage to the coils to damage them. I don't know its full design, but this sure seems possible with its internal oscillator, in my opinion.

They are made to increase cartridge sales :-)

Also, make sure a wire didn't break off inside your interconnects RCA's ends.
