I'm selling used tubes from my collection.  All are guaranteed to be operational.    I've included good-faith estimates on their usage since I don't have a tube tester!)

1 matched pair of Siemens 12AU7 (from Upscale Audio)- #30.00 (Estimated 500-1000) hours.  Clear yet so smooth!

1 6H23nEB/EV (from cryo'd from Cryoset). $20.00 (Estimated 500 hours).  Bolder, more dynamic in the 6922 position.

1 TAD 5AR4/GZ34 rectifier (cryo'd from Cryoset). $15.00 (Estimated 500 hours).  Very open sound stage while retaining great tone.

1 matched pair Gold Lion 12AX7 (cryo'd from Upscale) 30.00. Less than 500 hours) Rich, lush emphasized midrange in my system.  Highs not rolled off, just more prominent midrange.  I've gravitated towards a more balanced system, but it will work for you if those are the traits you are looking for.

Packaged deal: All for $80.00 shipped Priority Mail.

Hey Mike,

Thanks for the interest!  Yes, I can sell the Gold Lions separately.  But I have to make a correction...these are not cryo'd  (copy error on my part).   And, of course, these are the Genalex reissues! But they are matched and Platinum graded
