Thanks . This is the kind of reports I have seen spread across the internet BB's. Great tubes with little reliability. In my case it was an expensive catastrophic tube failure from the Shuguang. I'm told that the Psvane T2 is a great tube. But your experience shows the same problem with it as the Shuguangs. It appears that in most cases, they fail at about the same time they are just getting broken in. This was my case. Though the amp was used, I could tell the amp had not really been broke in before I got it. (The owner said it had low hours on it). Tough the Gold Lion's sound good, I would still love to hear a set of tubes that was not as rolled off in the high end, like the 2 previously mentioned. But I am not yet comfortable with trying either of those yet, thus my question here.
