I have some tubes that I bought in 2005/2006 that I have stashed away for years and found with a recent clean up of boxes that my wife asked me to go through.  The tubes were bought from reputable dealers.
I have a quad of NOS Winged C EL34 tubes made in Russia.  I bought these for a Jolida 302B and briefly tested the tubes before I sold the Jolida due to upgradie-itis.  I stashed them away just to find them during my recent cleanup.  I do not have any equipment that uses EL34 tubes so time to find them a new home.  
Asking 
$220 $180 shipped for a matched quad (Continental US address). 
SOLDSelling a quad of NOS ECC83/12AX7 tubes labeled Trigon that were made in England.  
I bought these tubes from BES (that was the parent company for what is now Tubemonger).
According to the seller these were Tungsgram NOS tubes branded as Trigon.  I packed them away and never used them.  
I can let them go for 
$150 $135 shipped for the quad which is less than I paid for them in 
2005 2003.  
SOLDAdded 12/20/2019: NOS Ratheon EL34 tubes (made is Japan)
I found a quad of NOS Ratheon EL34 tubes (made is Japan) that were in my stash of tubes that I saved when I sold my Jolida.  The labels and tubes look to be in excellent condition.  I have added some pictures for your review.  Looking to get $150 shipped. 
SOLDAdded 12/22/2019: NOS Valvo ECC86 tubes made in Germany.
Re-added picture (1/10/21)

I also found a set of 3 ECC86 Valvo tubes that I bought in 2002 for a Wavlength Co-Tangent phono stage.  I bought the tubes as NOS and never installed them before I sold the phono stage.  I paid $75 + $5 shipping back in 2002 from Tubeworld.  I will sell them for what I paid in 2002, $80 shipped and I will eat the Paypal fees.
