Yes, if you dont mind low gain and high drive requirements as well as
neutralization. The Europeans often use Thompson or Seimens triodes which
are not easily found surplus.
I had a contract several years ago to retrofit some French equipment
exported to the US with a similar spec Amperex which is still obtainable. It
had used some Thompson tube that was out of production.
