Schiit Freya + emits a high pitch squeal when using tube stage

Hello,

Bought my Freya + back in April 2020. I mainly use the tube stage. After a few months of use (total of less than 30 hours of use), I started hearing a low volume, high pitch squeal coming from an area around the tubes after an hour or so of listening. I swapped the tubes around and it didn't resolve the issue. If I switch to passive or JFET stage the squealing sound is no longer present. I contacted Schiit and they had me send the unit back (without the tubes as they told me to exclude them) for repair. I received the unit back with a note stating they fixed the problem and burned the unit in. After several hours of using the unit again, the noise is back. Has anyone experience this with their unit? I don't want to pay to ship the unit back to Schiit a second time.

The older units had problems with noise and microphonics. Perhaps this is still the case. I wont retube Schiit products for this reason.

For over 20 years I have sold old stock vacuum tubes on a retail basis and also provided bulk stock new production to manufacturers. Over a 2 year period all of the noise/microphonics issues I had with hundreds of 6SN7s and, I believe, 12AU7s sold were in Schiit products. At this point (probably 3 years past) I was done and stopped selling to Schiit users. The OP asked for opinions and experiences and this is what I gave him. The few instances I have heard Schiit products I thought they offered a good value but had a higher level of noise than what I was used to with similar products. My limited exposure to Schiit users has not been positive and I would expect higher than normal service issues with these products. Do a search on Schiit products and experience this "myth" for yourself.
