I likewise purchased my Mullards from Upscale - good place to buy them.
How long did it take for your tubes to ship from upscale audio? My order still says awaiting fulfillment from 2 days ago/
Are these the mullard tubes you guys have?

Did you guys get the tubes cryogenically treated?
I consider to buy WA7tp. And need some advise from users. How much it will improve from standard power supply, in case that I use its stock tube for WA7tp?
Which area does it make an improvement (sound stage, clarity, details, bass, mid, high)?
I have no idea about tube, and when I search in ebay, I found thousand of tubes and not know which good which bad. Noted that I live in Asia, and not comfortable to order tube from on line store in US.
Thank you for any comment. And will be more appreciate if anyone can recommend 12AU7 tube on Ebay with good performance
