Schitt freya preamp hum- how do I get rid of this?

How many inputs do you have connected? are any TV or cable?

You may have a ground loop fault. Turn everything off, unplug all inputs, leave output to amp and speaker connected. Turn it back on, if the hum is gone then it's one of your inputs. Reconnect one at a time.

Other method to check (NOT a recommended fix) is to lift the ground on the Freya power cord.

I'm always surprised how many people suggest call the company which is pretty much my last resort.  first they don't answer, you punch 14 buttons and end up leaving a message. When someone does call you back it is a clerk to take a messge.  but I'm glad it is working for some. 

In this case, I doubt it is the Freya, I agree with deadtrader, you have a ground loop.

Jumia I have the same issue with my Freya plus , one of the JJ Tube is defective, It Hum then blew up, I called Schiit, they sent me 1 set of JJ tubes total of 4.Call them they will take care of you.

Noise problems are common on this preamp. In fact I refuse to retube them as my experience has been terrible with with this brand. In fact the only returns I got for over 2 years (with probably over 250 6SN7 pairs sold for other components during this time) both came from this preamp. A hum from a bad tube is kind of unusual in my experience and some of the noise problems I have had reported were unusual and not typical of N/M. To make matters worse, tubes often get noisy quickly. I hope you have good luck and fix the problem, but I felt I should share my experience as a tube seller. I wouldnt waste my time and if the next set of tubes doesnt fix this problem I would demand a new unit.

I am not at all familiar with the Schitt pre, but, fwiw, from what little I have read from people who own them, they seem to be happy with the unit.  Does that preamp have a tape/monitor selector?  I was running a SLP90 that had less gain & a noticeable hum when the switch was in 'monitor'.
