Terms of Sale:
1. We promise to honestly represent our tubes. Of course, we are often at the mercy of the people WE buy from. Because of this, we offer a ten day money back guarantee on our tubes. We make a small mark on the tubes for identification. After the ten days, this is easy to remove with kerosene or other solvents or by just lightly scraping the glass with a razor blade. We reserve the right to refuse a refund for any tube that has been damaged. As long as it tests the same as when it was shipped, your money will be refunded.
2. We test all our tubes on Hickok or Sencore testers. Any numbers on the tubes, however, are reference values and not in any electrcial units.
3. Tubes are sold as New (recent manufacture), NOS (New Old Stock), or Used. Please note that NOS tubes do not always have perfect lettering. They may not have been stored in tube boxes and may have been handled on several occasions. If perfect lettering is important to you, you should say so. There will be an additional charge for hand selection. NOS tubes may also show deposits in the bottom. Many manufacturers 'burned in' their tubes so evidence of some use does not disqualify a tube as NOS. All our used tubes, unless otherwise noted, test strongly. This means that they have a useful service life ahead of them. We will not sell 'marginal' used tubes. All tubes are US or European unless otherwise specified.
4. Shipping is a fixed $7 for 'Priority Mail' for shipments up to 1 lb. First Class mail is also available. Insurance is $2 for the first $100 plus $1 for each additional $100 of insurance.
5. Terms of payment are check or money order in advance, Paypal, or credit card..
