Cleaning out my closet of extra tubes (more to follow). The companies I purchased from are listed.
Ruby (Shuguang) & JJ Tesla 12AU7 & 12AX7s
Ruby (Shuguang) 12AX7AC5 HG+ - AnalogTubes - matched pair - $20
Ruby (select Shuguang) 12AU7C HG - matched pair - AnalogTubes - $15
JJ Tesla 12AX7/ECC803S (long plates) - matched balanced pair - Tube Depot - $20
JJ Tesla 12AU7/ECC82 (short plates) low noise, matched/balanced pair - Tube Depot - $15
These have less than 80 hours on them (much less for the Ruby 12AU7); I bought them for my survey of current production tubes.
I liked these better than the Mullard, EH, and Tung-Sol re-issues. The Genalex were the best of all but twice (or more) as expensive. The Ruby/Shuguang resemble NOS Telefunken in style, the Tesla resemble NOS Mullards. I actually liked the Ruby/Shuguang better than the Psvane, the latter seeming overly smooth, "slippery" in sound (kind of like Teflon caps).
Paypal and first class USPS shipping included.
All four pairs for $60 with Priority Mail shipping.
Have an all positive rating of "390" on A'gon. under same user name.
