With free shipping, we cannot combine shipping. If you use eBay incorrectly, we can only combine shipping manually and ONLY if you notify us. To correctly combine shipments you must either use the add to cart feature or request total from seller feature. If you create multiple transactions or use checkout multiple times and over-pay for shipping, we will not automatically refund you. If this happens it is fully on you to let us know that you were overcharged and we will manually refund you less the fees we were charged on the over-payment.

We guarantee all of our shipments, but we do ask that our customers wait 3 months before we grant a full refund due to a lost package. We have shipped thousands of items internationally using First Class Mail and while we have had plenty take months to arrive, we have almost zero packages ever go missing. DEPENDING ON YOUR COUNTRY’S POLICIES, YOU MAY BE RESPONSIBLE FOR IMPORT TAXES WHEN ORDERING OVERSEAS FROM US. WE ARE NOT RESPONSIBLE FOR ANY TAXES, DUTIES, OR CUSTOMS FEES. WE WILL NOT FALSIFY THE VALUE OF AN ITEM TO AVOID CUSTOMS TAXES. DOING SO IS ILLEGAL AND CAN RESULT IN SEIZURE OF YOUR ITEM. Terms & Guarantee Payment is due within 4 days of purchase. All of our tubes are 100% guaranteed to arrive as described, test as described, and sound as they should unless otherwise noted in the description. We even guarantee our tubes to arrive without having any sound-quality issues like microphonics or noise. You may return the item for any of these reasons up to 14 days after receipt and we pay for the return shipping. We do not accept returns for buyers remorse or in the even that you ordered the wrong item, please be sure before placing your order. PLEASE NOTE – WE DO NOT ACCEPT RETURNS FROM CUSTOMERS WHO DECIDE THEY DON’T LIKE THE SUBJECTIVE “SOUND” OF A TUBE. Tube rolling is a lot of fun, but we cannot predict if you will think a tube is too “thin, bass heavy, etc” – everyone likes something different. Any returned tube must test within 10% of the original value. Any larger variation would indicate many hours of use or abuse and voids our guarantee.

Sylvania 6EL4A/6BK4C vacuum tube

exact item shown – I no longer have a tube tester – a few years ago, I bought some “attractive” tubes from a tube seller at the end of a swap meet, I was going to use them to make paper weights (machine an aluminum base, they look cool), and I did make some, but I got busy and forgot about them – this was in the box of tubes I bought – Note to me: 4th thin drawerI normally ship within 24 hours of your order, but the post office does not always initiate tracking when I put the packages in the drop off box.
