TAD vacuum tubes?

Thank you, @noromance ​​​​​@jond .  

Thanks to all for the input.

I am way good on my over supply of 6922/6DJ8s and 6SN7s and EL84s, but I am thinking ahead about the dozen EL34s for my Cary V-12.  Without any intent whatsoever to start a political discussion, I presently do not want to purchase tubes manufactured in Russia, and I am wondering what the options will be when the time comes.  I probably will not be able to justify the price of a dozen vintage EL34s, so when the day comes, I may have to park that amp and break back out my smaller Cary amp that only uses four 6550s, of which I own three different  serviceable quads.  

Thanks for the input.  When the time comes I'll need a couple of matched sextets.
