Linlai Elite vs Psvane Acme 845

I am unable to answer your question in full, but hopefully I can give you a response that is nonetheless valuable. I haven’t heard a comparison, but I’d be willing to bet the two are almost identical with some slight variations at best. Just as some of Shuguang’s best engineers branched off and formed Psvane, Psvane’s top engineers left and formed Linlai. That said, the quality control has since dropped from Psvane’s tube lines such that Grant Fidelity will no longer carry them.

I’ve never owned any Linlai tubes, and the Psvane ACME tubes I have owned (845 and 300B) never gave me any problems or were never short of spectacular. But if I were able to buy Linlai Elite at the same price, I’d probably find myself springing for those instead. 

Can the Acme tube be bias at 80-90ma, extreme pushing the tubes to the highest level,  from what i heard it does red plate when it’s being push too the maximum. In my situation if i need power, would the Linlai  works best for my speakers?  Specs wise, 100w dissipation and metal plates for the Linlai. 

I'd also be interested in hearing from those who've tried either tube. Yes, I too have heard of Acme 845 tube failures, mostly with Line Magnetic amp, can't recall the forum, perhaps Whatsbestforum.

I don't know if this has any bearing on 845 tubes, but I have experience with Linlai Elite mesh and solid plate, Psvane WE101D in my Coincident Statement pre, and Psvane Acme 300B in my custom build 300B monoblock amps. Linlai solid plate best with Psvane a close second, Acme 300B wonderful tube, way superior to prior Shuguang Black Treasure.

Reportedly, there were problems with early Linlai Elite 101D tubes, since rectified, I did have failure of one mesh plate.

Based on above specs you mentioned, it would appear the Linlai 845 should be more rugged.

I don't think Grant stopped carrying Psvane because of excessive failures, this was far more about marketing conflicts of interest

Back to 845's. I've been running 845 amps for well over ten years now, experienced failures from TJ Fullmusic and KR, never any issues with either Shuguang or Psvane, the Psvane Black Bottle special editions purchased at Grant Fidelity I'm using at present are best 845 I've heard up to now.
