Sorry to hear that.
Actually, the tubes I use are the Psvane EL34PH (still the same quad as last year), not the Type II.
Grand Fidelity does do testing prior to shipping from China (I believe they have the Amplitrex as well, it mentioned on their site somewhere).
This is why I don't recommend buying Shuguang or Psvane from Ebay, seems to be way too many failures for all their tubes, not just the EL34's.
Right, sorry to confuse, my point was I am hesitant to buy PSVANE again. But.... Grant Fidelity cost is worth the testing and matching they are doing, instead of messing around with various Chinese re-sellers.
Also, the New Sensor KT77 (Genalex re-issue) is a tube you could consider too. My amp has a mod for EL34, but this KT77 is quite a tube. I may try them in this SET amp.
