KOTriode,
We had this conversation before. It is not what I regularly experience. The 20% of faulty tubes is astonishingly high number for this tube and if he has this ratio and did not change his suppliers then he must be crazy. On the good side you know where his 20% of faulty tubes go – you bought them!
On another note, your amp manufacturer makes OTL with 6C33C. The OTLs are very different animals and the requirements for the tube are much tight. Still, no matter what you do the OTLs with 6C33C do burn the speakers, soon or later but they will.
Anyhow, I do not agree with that 20% of faulty tubes assessments. It just does not correlate with what I experience with this tube. I have the Golden Grid tube already in here, I got a dozen of them, but I did not open them up.
BTW, when you say that the “tubes does not have current” what does it mean? If you keep dropping bias then you do not have current rising?
