Hi everyone , I bought quite a bit of Tesla E88CC Tubes white pin. I have tested all of them on my tubes tester, for shorts and for life, they test extremely well. In my ARC ref 1 they sound magnificent, they are so natural it's incredible. The tubes seem to like my ARC Ref 1, no issues with them. As soon as I put them in my amp ARC VT130 SE, in the input stage they seem to last no longer than 20 minutes before you start to hear popping and the channel dies out. So I remove them and install 6H23P-eb and everything is fine again. I then test the removed Tesla on my tester and one of the tubes has shorted out????
Does any one know what's going on ? It has happened twice now..............
Thanks

The Audio Research VT 130SE calls for the use of 6922 in the input section, 2 on each
channel. Isn't an E88CC the same as a 6922 ??
Yes, I believe so. In that case it shouldn't be exceeding the ratings of the tube. Sorry, don't know - you could measure the operating conditions yourself just to be sure.
I think the old E88CCs have always had gold pins:

Compared to Russian 6H23N the E88CC Valvos sound more warm & full.
Tesla also made them with gold-pins:
