I think if i have 5 units of Pro ICan on at least one unit my WE396A will work.
It's too random, some units are more tolerant to swap tubes than other...
I think IFI don't test any other tubes, it meant to be working only with NOS GE5670.
That's bad becouse i own cheaper (half price of Pro ICan) tube amp and i could swamp tubes almost without any restrictions.
the last 2 sets of tubes are of our GE5670 bought at ifi pro, it is they who provided them, and they do not function,
