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

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.

In two years you replaced the tubes in two Freyas. This is what is relevant, not other models.

Terrible?

Given the rather unpredictable nature of tubes sometimes, varying from very reliable and operationally stable to being dead on arrival and everything in between, a tentative intuitive statistical consideration would suggest that your experience with Freyas is well within the bounds of acceptable.

More data - including tube failure for Freya, actual user experience using tubes with Freya, brand of tube, type (new or NOS or used) etc would be required for a more robust conclusion, but terrible I think would not be one that I would suggest based on those numbers.

Should I be incorrect and a systemic issue be found that suggests a design flaw, then again, I would reiterate that Schiit really needs to hear about these things. Their authorized dealers may have this responsibility - and it is in their own commercial interests to report them.

For those people with email, drop Schiit a note on their help and support portal. And they do supply a 5 year warranty on the amp.

Off topic - what is really surprising to me is that no other 6SN7s have failed during this two year period. That in itself is quite remarkable given your large sample size. I know 6SN7s are very good, but that is quite an endorsement.

sell the f****** and buy something else..

Vegas odds are the wear and tear items “tubes” are defective. The Freya is a solid unit. 

Well I cant say that there were no others failures just not immediate requests for returns for noise problems. After this rather unusual event I did a search to see if this seemed to be a trend and other customers had reported the same problems. Dont get me wrong I think these products represent a good value, but the types of noises being reported were unusual. In fact I kept track of the Schiit specific tubes, tested them again for noise/microphonics sold them and had no problems. 

I understand anecdotally that Schiit had some quality issues (either build,or design or both, whatever) in the past but that this has been largely resolved and they have been spitting out some affordable and robustly engineered products recently.  Must annoy audiophiles a lot.

Which leads me to think that they are taking notice and act accordingly. Perhaps its an on-going process and as with many things this usually takes longer than anticipated.

But this is the first I’ve heard of issues with Freya +. Maybe I blinked, or people do the right thing and return the product to the dealer or to Schiit.

And they must have sold at least a few hundred units worldwide since they were released a couple years (?) ago, so that’s pretty good.

I don't own any products by Schiit but something like Freya+ would be one I'd consider if only it was a dedicated tube pre.amp.
