I spoke to Mark O'Brian about the first (KT-77) failure, but not the second (E34L) one. I shot him an email about that one yesterday. He did not have an answer for the KT-77 failure, nor should he.
The affected tube locations were different for the two "flame-outs". Had it occued in the same location, I would have suspected possible circuit troubles.
In this month's Stereophile, JA measured Atlas clipping at 101 watts (single channel driven) and 86 watts (both channels driven). That's driving EL34's very hard. The Atlas is similar to the VTL ST-85 in this regard.
I know from experience that the Tesla E34L (no longer produced by JJ in that form) was a weak tube. I popped some in a Marshall head in the mid 90's when it was selling for less than $45/quad. I don't think it can handle the estimated 525 volts. You get what you pay for.
I'm keeping my fingers crossed. I don't want to be popping tubes all the time.
