Help,Anyone have Jobs contact info for repair?

Hi all, my job 225 is making some right channel noise so I want to send her in for a checkup but can't find any phone numbers. Thanks in advance for any help.
Did you do any trouble shooting? If not, try swapping all your cables on both channels. Having a broken or bad cable could be the cause of the noise. If its not a cable problem, swap your components until the noise goes away just to be sure the problem definitely your amp.
