Amp Hum (9KHz) Problem

I've recently experienced a high-pitched buzz/hum when playing through my 65 BFDR. Not the 60 Hz hum. This is around 9KHz (when I record the sound and use an parametric EQ to cut 9K the sound decreases significantly). I can actually hear what sounds like a clock ticking through the amp. When I turn the amp on but don't have the guitar plugged in, I do not hear the sound. I play a Tele and Strat with single coil pickups. Changing positions does seem to attenuate the hum. When I plug into my Great River preamp (DI), I also hear the hum but not as loud, but not the clock sound. So I'm assuming that I am picking up some sort of noise/radio wave through my pickups. I've never had this problem before. It's driving me nuts. When I'm recording guitar tracks this 9k hum is killing me. Any suggestions would be greatly appreciated. Thanks.

Where are you? Are there any cell phones in the area? Do you have sprinkler controllers, alarm systems, or children's toys nearby?

I'm recording in the basement of my house. And yes to all of the above: sprinkler controllers, alarm system, and my son's toys. It's just that I've never had this problem before. I just had my amp serviced. Is this just a really bad shielding problem?

If the only thing that has changed is the amp tune-up, I would suspect that....
