Best 845 tube out there?

UPDATE ON TJ 845.. WARNING !! DO NOT TRY THEM... my matched Quads did not work...
I will now have to stick with the PSVANE 845.
I don't think the TJs are same spec as RCA anymore.

I have the audion elite 3 box and have the 845b, shuguang 845m and just recently the kr845. Overall in the context of the rest of my system the kr845's are the winner. I prefer the b over the m too because i find it more "beautiful" in the midrange, though its not as robust as the 845m, i like its more "liquid" a presentation. The kr845 has a wonderful sense of "flow" that is very appealing and seems to my mind get alot of the parameters of music "right". It is not perfect but like i already said, it has the most plus's with the least amount of - tives. I found the kr's presentation a more palpable one then the others too. I would say the kr845 is easily in another league than the other two. To me it is a finely bred racehorse while the others by comparison are just "good".

Hifi223, what "didn't work" with the TJ? Did they run too hot like that had been over driven with too much filament current?

What did you tube supplier say about your experience?

Hi Brf, i had 4x TJ 845 to try or test (i'm a TJ dealer in Australia). They were going into my melody custom Mono Blocks.
Tj 845 didn't last 5 seconds on my monos, one pair were really noisy, making crackling poping noise, they other pair blew-up straight away, also blew fuses on my amp. I'm still waiting for my supplier in Hong Kong to reply to me, i suspect they are not RCA specs as claimed. So, back goes the PSVANE.!

Did the TJ 845 come with a spec sheet indicating the tube's actual performance?
