LinLai WE 300B or the LinLai Global Elite Permaloy 300B tubes ?

@charles1dad , Yeah, Israel trashed my Linlai 101, he seemed to not know of them when I initially spoke to him, only added he doesn't like mesh plate tubes. He also told me my particular pair were bad, I had them tested on Amplitrex tester after getting back linestage from him, they were in fact not bad. Israel telling stories, likely including mine as failed pair. And yeah, I'd agree the Psvane WE are plenty good, Linlai is just another flavor, I go back and forth.

Power tubes for amps seem to be the vast majority of tube reliability issues. I've been running tube amps and preamps since around 2000, only tube failures I've experienced were KR845 and TJ Fullmusic 845 in Art Audio amp. Not worried so much about pre tubes or drivers in amps.

@liquidsound  Here's to a speedy recovery. And as Charles pointed out, hopefully no long haul problems.

Thanks to all for recovery wishes !  I don't wish this crap on anyone !  I'm just now crawling out of this tough 11-days of profound fatigue, 100+ temp, achiness, cough and loss of smell/taste !  First morning with no temperature !  

Just a quick note about reliability - I've never had a problem with my lowly JJ 300Bs. I've been running them about 10 months. I know they're not considered a top-tier tube, sound-wise. I guess I should consider myself lucky that I can be satisfied with them, since I've never had a chance to compare them to anything else. 

At the risk of further complicating the issue: while both Takatsuki and EAT comfortably beat my TJ Full Music meshplates, in my Wavac EC300b there is a strong effect dependent on the recifier tube used. While the EATs prefer to be driven by Tungsol KT66s, the Takatsukis love to be driven by the cryo version of Svetlana Winged Cs. I have experimented with a large range of other 6L6GCs such as JAN Philips 7581-as, Shuguang coke bottles, Tungsols et al but the above combinations win out. The EAT/KT66 combo has better dynamic range for the price of slightly harsher sound, the Takatsuki/Winged Cs major on resolution and timbre for the price of somewhat lesser ooomph. In the world of tubes, trial and error is indispensible
