tuner to tube preamp


I have connected several tuners to my tube preamp and I am getting a light fizz noise, only with the tuners.i know that the stations are coming in clearly. the noise is not there with other sources. I have changed out the tubes also.
kind of a rice krispies noise. moving cabling around doesnt help much. could this be my power source? i'm actually in a hotel room.

this has to be some sort of electrical interference phenomena.
on all stations, the distortion is there, but with a cd player through the same rca inputs there is no noise. i'm just using a wire antenna, it is picking up stations well.
