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

Hi Charles,

I understand it must have been frustrating back then to experience all these failures. But that is more than 5 years ago and the tubes are now being manufactured under my lead longer than they had been in the old company. Would we still have the same issues we would not have survived that long. Maybe it is time to stop repeating that experience form the past.I think the last 5 years have proven that our tubes are not prone to failures anymore.

Best regards

Thomas

Well I can only testify to what my real experiences were with the Elrog 300b. Beautiful sound but fragile.   I clearly pointed out that mine were the first/early generation tubes and I offered no opinion of the current production Elrogs.

If under your 5 year ownership of Elrog you have resolved the reliability/early tube failure issues then that is wonderful and encouraging to know. I wish you continued sucess.

I have an Ancient Audio custom 300b SET. It uses two 300b and two ECC88. I tried BlackTreasure, Sophia Royal Princess, Takatsuki, and KR Globes - in that order - each representing an improvement in sound quality. I loved the Takatsuki (simply sublime), but experienced reliability issues; and unlike Charles' experience, I was less than happy with the company - especially considering the cost. The KR Globes kept most of the Takatsuki sound quality, but were more dynamic. I would love to try the AudioNote 4300e (made by Psvane, I believe) or the WE reissues, but otherwise plan to stay will the KR Globes. Most recently, I upgraded the ECC88 to Telefunken and was surprised by the improvement. 

@gsm18439,
Interesting how your Takatsuki to KR audio 300b experience  parallels my Takatsuki to EML. As much As I enjoyed and respect the Takasuki there was no looking back once I got the EML XLS. And as you note with your KR I did gain in dynamic performance (Even though the Takasuki  itself dynamic). The high End eastern European 300b is just built in a heavy duty manner.

A couple of quick thoughts.  I also had unacceptable tube life from the first generation Elrog 300Bs, but sonically they were a cut above every other tube I tried in my Frankenstein amps, including Black Treasures and the EML XLS.  I did not evaluate the Taks in my amps.   I do think that it is time to acknowledge that Thomas has addressed these issues, although testimony from a user who has found the new Elrogs to be reliable in the Coincident amps would certainly be welcome.  I've moved on from 300B's, but had I not, I would give the new Elrogs a try.  They are that good!
