KEN-RAD VT-225 307A. MILITARY VERSION BLACK GLASS, LIGHT USE. TESTS STRONG.
All tubes are fully tested for leakage, shorts, gas, life, and mutual conductance. Then they are matched according to brand, properties within the date of production, and mutual conductance.
Matches are based on mutual conductance. I use two different, calibrated Hickok 539C'S and/or, a Weston model 981 type 3. If they pass the testing, they will be sold with test data for that tube.
If the tubes aren't matched within 6%, I will acknowledge that in the description.
I also offer a money back guarantee. Buyer pays return shipping for local pickups, I advise you to bring the electronics that the tubes are going in, within reason.
Guitar amps, small radios, etc. I will allow you to test them on site, but you will be responsible for any product damaged by a faulty electronic.
I'm an honest seller and I stand by my product.
Feel free to message me with questions.
