Question on Chinese Tubes Shuguang KT-88-T (Nature series)


I bought an amp with the Shuguang KT88-T  tubes. One month after I bought it, a tube failed. So now I have 3 very good tubes which I cannot find anywhere but China. Just perusing through posts about this tube I have discovered that these tubes have had reliability issues. In my case, it took out a channel in my amp which had to be sent back to the builder to be repaired. I don’t want anymore of that. Considering the past problems of poor reliability & my own situation which was expensive, I wonder if its wise to even buy one more of these Shuguangs and take the chance on tearing up my amp with it again. BTW the amp had built in protection but it didn’t work. Don said he had put in more safety measures when it was repaired. . But I’m concerned. . What’s your thoughts. Abandon the Shuguang? Try another one?

Just a NOTE:

Whatever you do, do not do any tube business with "CHINA-HI-FI" I ordered a matched quad of KT88Z's a few months ago. When tested, I found that all four were defective. It has taken months to get this resolved. Now YOUN LEE claims to have issued a refund, but did not state through who. I checked all of my credit cards and PAYPAL. No record of any refund credit issued. This is either just a scam or a "delay and evade" tactic   BEWARE of this company
