Elrog 300B vs Takatsuki 300B tubes

Charles,
I received my replacements about a week ago and have listened to them sparingly while awaiting delivery of the PS-10 so I can limit the voltage going to the amps. That said, the replacement tubes most certainly sound better than the originals as they sounded prior to failure.
When I replaced the failed elrogs with my Psvane T black bottles, I was surprised to find that the Psvanes were almost indistinguishable from the Elrogs. This was in sharp contrast to my initial reaction to the Elrogs, which was that they were head and shoulders above the Psvanes. The inescapable conclusion is that the Elrogs really degraded with use prior to failure. Prior to failure, I knew something was wrong. The system had lost its magic, and I had no idea what was wrong.
Anyone else experience anything similar?
Apart from keeping the voltage down to 117, anyone got any more tips on the care and feeding of the Elrogs?

I was interested in buying a pair of the Elrogs and contacted trueaudiophile recently. Unfortunately, they no longer carry them. The guy I talked to said it was a nightmare dealing with all the failures and warrantee issues. I hope someone will carry these tubes once the failure issues are resolved.

Trueaudiophile recommends the Takasuki's over the Elrogs now. I guess it has more to do with reliability than sound quality, but according to TA, the Takasuki's come closest to the vintage 300B sound.

Although I have never heard the Elrogs (and I trust Charles' 'ears'), I am a fan of the Takatsukis.

I bought my Elrogs from True Audiophile. They distinguished themselves with excellent responsiveness and customer focus. I also heard the horror stories in their attempts at taking care of their customers who experienced tube failures. I can say they did everything they could to help me. Indeed they did all I could expect of them and more. It would seem the relationship between TA and Elrog ended on rather strained terms. It will be up to Elrog to meet market expectations with respect to both sound quality and product longevity vs. other premium 300B offerings. By all accounts, both the EML and Taks are not far behind the Elrogs.

I had a pair of Elrogs fail, and they supplied a replacement pair promptly. That is about all I could ask of Elrog. If this pair fails, I am quite sure I will move on,probably to the EMLs. On the other hand, I have no reservations about dealing with TA again. They proved themselves to be a truly customer focused vendor, in my estimation.

The Elrog tubes are very good, and we all want them to get the issues rectified. But at the end of the day, most of us won't be investing in tubes that only last a few months. And, Elrog also should nurture distributors of the caliber of True Audiophile. TA showed themselves to me to be a bunch of good eggs, in my opinion.
