845 Tubes

The Grant Fidelity website lists Psvane & Treasure "special edition" 845s , they have larger bottles and black coating. Has anyone tried either of these and can offer impressions? Also, they are now carrying 845s by prior Psvane personnel manufacturing under the brand Linlai. Has anyone had any experience with the brand - sound, reliability, etc?
Thanks. According to the GF website the Linlai tubes are made by Psvane "defectors"
I also can second the Psvane 845s. I have used the Psvane WE845s and upgraded to the ACME 845s..great tubes and great people to work with. Rachel is great.
@facten  yes but the defectors might only be the principals not the people who make the tubes. My wife made very exotic vacuum tubes for the military and it took her years to learn her craft. Believe it or not our military still uses vacuum tubes.
