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

If you consider that you have a faulty product, the best thing to do is to let the company know and they will do what good American companies always do.

They actually want to know if they are shipping defective products so they can fix any quality control issue so it will never happen again.

And hear about what may have been an innocent mistake first-hand rather than reading all about it in the forums.

A competitor with ill-intent may characterize the Freya as being "cheap" and therefore inherently faulty.   Ouch.

I agree!

Is the hum through the speakers, if so, both speakers?  If it is through the speakers, but only one speaker, try changing the tubes from left to right.  If the hum changes speakers, you know it is a bad tube.   If the hum doesn't change speakers may be a bad unit.  But one last test, gently tap the tubes, and if you get a loud pop it may just be microphonic tubes.   

The above testing should just take a couple of minutes.  If it doesn't help, be sure to send it in for a replacement.

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.
