I swapped Shuguang Black Treasures into my Ayon Spirit 2 , enjoyed the sound but 2 failed and I went back to Gold Lions rather than trying the Treasures again. I subsequently tried Psvane T2s , again liked the sound but one failed 3 months in. I could have purchased another Psvane but went back with Gold Lions. Although I know that any tube can/will fail I didn’t want to run the risk with the Treasures or the T2s but that’s me; only you can decide what’s best for you.
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?
