Description

This lot includes 5 vacuum tubes of various brands, all tested and in good working order, plus 1 bonus Telefunken that does not test good. The 12AT7 model is a classic choice for audio enthusiasts and collectors alike. These tubes are perfect for use in vintage audio and video equipment, as well as modern electronics. Whether you're a seasoned collector or just starting out, these vacuum tubes are a great addition to any collection. Also included in lot is a Telefunken 12AT7, but it tests weak, below the TV-7A acceptance value of 50. So it is only included as a bonus, non-working tube. 5 tubes test good on both Hickok 6000A and our newest addition, a calibrated TV-7A/U. See measurements below.
