Just another reinforcement of my belief that Tung may be God.
I'm having a hell of a time getting a 12AX7 and 12AY7 that aren't microphonic for my 5E3. I'm actually considering NOS.

Hardly. I would bet that Ch0jin has forgotten more about electronics than I'll ever know. I've just been doing this a long time and am OCD/pedantic about minute details.
FWIW, I suspect a lot of new production 12AY7s are nothing more than weak-testing 12AX7s. NOS might be your best bet. Look for 6072 tubes, they are industrial-labeled 12AY7s. They'll probably outlast new production tubes by a great deal, and will probably sound better as well. If you find 6072 tubes, be prepared for sticker shock.

Aww shucks, thanks for that Tung.
The reality is that vacuum tube technology (aside from CRT's) was off the syllabus by the time I studied electronics. All I've learned has been from the older guys I worked with like 15-20 years ago, and recently, from the intrawebs.
You could say I was raised "Solid State" and converted to "Vacuum Tube" in my late 20's.
Just received my package from thetubestore ! Man, $70 shipping really does make those couriers hustle. From Ontario to Sydney in 5 days. That's got to be the fastest I've ever received anything from that far away
Now I just have to wait out the rest of today at work.... (or perhaps a few more days until I build a bias adapter so I can see how the new tubes bias up. Working in a 1 Ohm resistor inside the chassis looks far too much effort. PCB's huh.)
