MATCHED PAIR (2) SYLVANIA GB-5814A / 12AU7 GOLD PIN, MATCHED DATE TESTED ON 539C. GOLD PIN GREY PLATES HALO GETTER MATCHED DATE CODES 1. 3550/3500 MUTUAL CONDUCTANCE 2. 3600/3600 MUTUAL CONDUCTANCE VERY RARE TUBES. CREAM OF THE CROP 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 539CS 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 arent 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. Im an honest seller and I stand by my product. Feel free to message me with questions. GlassBatman8

These arevery good. Your tubes will be shipped within 5 business days, usually faster by USPS First Class I combine shipping and will refund excess shipping charges if multiple orders are shipped together. Thank you.
