Psvane 2A3 Tubes

[Bigsecret]

I'm curious to find out who else has had problems with Psvane 2A3 tubes? I have tried both the 2A3T MkII tubes and newer WR2A3 tubes and they are some of the best tubes I've heard in my DNA Stratus but, out of 9 tubes (from returning and replacing) I found only ONE that did not end up sputtering/spitting/ticking/squeaking. Noise can start as soon as 2 hrs of play or up to 50 hrs. But, I am now convinced that the ONE that didn't make noise...would have.
 
I don't see anything on the web about anyone having trouble with Psvane tubes in general and realized it may be just their 2A3s that are probably very low production runs. 
 
Anyone else having problems or, alternatively, having great luck with these tubes?

I have two pairs of Psvane 2A3B and one tube from each pair has sputtering/spitting/ticking/squeaking problem. It is ashamed as it has nice tone.

I keep checking this thread and can only conclude that I have been singled out by the Tube Gods to tortured by making it impossible to purchase more than one Psvane 2A3 tube that doesn't end up sputtering, spitting and making odd noises. Upon giving up, instead of asking for a replacement tube I asked for a refund. They said they would only send a replacement and I would have to pay $40 shipping. That may sound fair except that I have paid over $150 returning tubes that made noise AND I'm not asking for a refund for the other tube (the ONLY tube out of 14 that has not made noise) - a tube that I have no use for since I need a matching pair. 
 
I have only used these tubes in my DNA Stratus amp and have 2 pairs of NOS RCAs, pair of NOS Sylvania, pair of EML Meshplates, stock Shuguang tubes, Shuguang Nature Sound tubes and NONE of these exhibit any problems. The Psvane factory says they cannot duplicate the problem on the tubes I have returned and believe it is my amp.
 
Just venting I guess. And, if no one else is having these problems then...
