Noise issues with phonostages are often quite unpredictable and hard to figure out.
While it might be the case that certain gear is generally more susceptible to noise problems, it can also be the case that it is only more sensitive in certain applications; e.g., sometimes the problem can be cured by moving the location or orientation of the phonostage or interconnect cables.
I have a preamp with a built in phonostage that, in my setup (preamp on a shelf two levels below my turntable) I have hum issues, whereas that same preamp in another system is dead quiet with a phono cartridge that has a .05 mv output (my problem is evident with a .30 mv cartridge).
Hum generated from the power supply of the phonostage itself might be a bigger issue with tube linestages, but, again, when things are right, tube stages can be essentially dead quiet (like my stand-alone phonostage).
I have heard both solid state and tube units that had noise issues. I don't think "type" tells you that much about proclivity to be noisy--one has to actually try the unit. In any given application, a unit that is otherwise known to be quiet may behave badly. For example, a friend's very expensive Boulder phonostage buzzes badly from over the air interferene (from lighting) where a tube unit we tried is quiet (Boulder is NOT known to be prone to ANY kind of noise problems).
