Pre amp noise

How can my pre amp be relatively quite one day and the next puts out a hiss, not a hum...tonight it's in the right channel
Pulled interconnects, tube etc

Thanks for ideas

If you switch tubes does it move to the left? Tubes will get noisy when they want to be changed..maybe thats it? or maybe you just need to run a ground wire from source to amp.

Next time it happens, power down and move the controls back and forth. You should also clean the tube pins and sockets. Are you sure it's not crosstalk? Whenever I play vinyl, I can faintly hear the tuner if it's on. Same thing happens with CDP.
