Sylvania 12AT7 ECC81 6679 Vacuum Tube Valve NOS NIB For Your Univalve

This new old stock, new in box Sylvania 12AT7 / ECC81 dual triode was tested on our Maxi Preamp II for shorts, gas, noise, transconductance and gain. There were no shorts, noise or gas and it measures as follows: Noise: -83.2 dB / -79.2dB (-92 dB is the Maxi-Matcher's noise floor) Conductance: 1877/ 1692 Gain: 48.3/50.6 where 50/50 is new/nominal. This tube has beautiful silkscreening; black plates; a top O getter and excellent flashing. It sounded balanced, had excellent frequency response and was very quiet in my Bottlehead, though this amp is not optimized for this tube type. BECAUSE OF THE BIZARRE, INTRUSIVE, PETTY AND DRACONIAN GERMAN PACKAGING REGULATIONS -- AND THE SEVERE FINES AND PRIVACY INTRUSIONS ASSOCIATED WITH THEM -- WE NO LONGER SHIP TO GERMAN ADDRESSES. WE WILL HAPPILY SEND YOUR PACKAGE TO A NEIGHBORING COUNTRY OR MAKE SUITABLE ARRANGEMENTS. IN 2021 WE PURCHASED 150,000 VACUUM TUBES. IF IT'S NOT LISTED, WE PROBABLY HAVE IT.
