As I continue to downsize my tube stash, I have 5 good European ECC81 12AT7 tubes to offer for sale.

NATIONAL/ RFT - New pair in brown boxes. Crisp red National Made in Germany logos. RFT made some of the finest affordable 12AU7s and 12ATs in West Germany that were often re-labeled by other brands. Small halo getters on the distinctive RFT single support. They test as-new and they flash when they power on, like a good Euro tube should.
$20 FOR THE PAIR.

AMPEREX - This is an older Amperex, probably 1950's, because the delta K TkP factory codes are between the pins rather than etched on the glass. No logo remaining, 4 seams on top, copper rods, and angled foil-D getter. Tests over 90% of new and flashes when you power it on.
$20 FOR THE SINGLE

CBS/MULLARD - This tube has an identity crisis. Crisp CBS Holland logo, but clear Mullard Blackburn B7B factory codes. 4 seams on top, copper rods, and angled square D getter. Tests at 80% of new and flashes when it powers on.
$20 FOR THE SINGLE

UNKNOWN - Partial logo says 12AT7 Great Britain and those are the only markings I can find. Black plates (uncommon on AT), copper rods, and large halo getter. Tests at 90% of new and flashed when it power on.
$5 FOR THE SINGLE OR FREE IF YOU BUY 2 OR MORE OF THE OTHER ITEMS IN THIS LISTING.

BUY ALL 5 TUBES FOR $50 WITH SHIPPING INCLUDED.

Feel free to ask questions.

Payment by PayPal with no fee.
Shipping via USPS 1st Class for $3 to CONUS. No International shipping at this time.

I will be selling many 12AT7, 12AU7, and 12AX7 tubes, mostly 1950's US military versions.
Let me know if there is something that you are looking for.

Thanks for looking and best regards.
