Be sure to read my policies below, and contact me before you purchase if you have any questions.
I have over 30 years of experience as an electronics engineer, certified electronics technician, and hobbyist, and have been collecting, buying, and selling tubes since the 1980s. I've been an eBay seller since February of 2000. This is the only seller account I have on eBay and the pictures you see are of the actual tube(s) you’ll receive (unless you are buying from a multiple-quantity lot, in which case the tube shown will be representative).
Tubes are described, tested, and presented to the best of my ability, subject to the limitations of the equipment that I have available (Hickok 539C and 6000A, and MaxiMatcher 2). Test results are likely to differ between your equipment and mine due to many factors. Tubes are not tested for noise or microphonics (however, I almost never have returns for this reason).
Do you have tubes to sell? Contact me with your inventory!
Return Policy
Unless otherwise stated in this listing, tubes may be returned within 30 days for a refund. Please keep in mind that while I do allow returns, my purpose here is to sell tubes, not to loan tubes for rolling. Any tube to be returned must:
a) still bear my identification stamp.
b) be in EXACTLY the same condition in which it arrived to you. Things which may invalidate a return: defaced or smudged print on the glass, bases scratched from retainer springs, cracked or damaged glass, damaged or missing boxes (where original boxes were sent with the tubes), and electrical or physical degradation from improper operation or handling.
Returns which do not meet the above criteria may be refused or may be subject to partial refund.
I pay for return shipping on all returns within the USA, regardless of reason.
You pay for return shipping if you are located outside of the USA. If the tube arrives to you DOA or significantly not as described (SNAD), I pay for return shipping.
International buyers, please note: import fees and taxes which you pay to your border and/or customs agency are not refundable by me under ANY conditions or for ANY reason, regardless of the reason for your return.
Shipping
Your tubes will be professionally prepared for shipping using all-new packing materials and will arrive to you in perfect condition. I've been shipping tubes for many years and know how to get them to you quickly and securely. International orders ship with proper customs documentation (and tax code or IOSS number, where applicable) to ensure that they're processed with minimal delay upon arrival in the destination country.
DOMESTIC:
Unless otherwise noted, free USPS shipping is offered on all tubes purchased with Buy-It-Now. Other services are available at additional cost. If you prefer a shipping method that is not listed, please contact me prior to purchasing. I can usually ship via any USPS, FedEx, or UPS method that is applicable to your ZIP code. If you need expedited shipping (Express, Next Day, etc.), please contact me first to confirm earliest available date of shipment, as cutoff times are generally early in the afternoon.
INTERNATIONAL:
USPS First Class Mail: This is the least expensive option but the availability of tracking is limited in many cases. It's available worldwide for packages with a value of USD$400 or less. Be aware that First Class Mail has been known to take up to three months to reach some destinations. If you select the First Class option I expect that you will be patient and wait three months before requesting a refund for “item not received.” If you require faster delivery please select an option below.
USPS Priority Mail: This option is available for shipments with a value less than USD$1000. It typically takes a couple of weeks to reach most destinations.
UPS Worldwide Expedited: This option is available worldwide for all shipments, and is required for shipments valued at USD$1000 or more. It is fast and reliable, with end-to-end tracking.
I can also usually arrange shipping with DHL at additional cost. Please inquire before purchasing if you have specific requests.
I ship to China and Italy only via UPS Worldwide Expedited, regardless of value. No exceptions.
Ebay places the burden of safe delivery on sellers, so I fully insure all shipments sent outside of the USA, regardless of value. Because I can insure only up to the declared value, ALL SHIPMENTS ARE DECLARED AT ACTUAL VALUE. You might owe significant import fees on higher value shipments once they cross your country's border – check with your border or customs agency for details.
I can ship to a domestic freight forwarder or other third party within the USA, provided their address is on the order at the time you place it.
GENERAL:
SIGNATURE REQUIREMENT: All orders valued at USD$750 or greater, and ANY order shipped via UPS or FedEx, automatically require a signature release upon delivery. Someone at your delivery address will need to be available at the time of delivery to sign for the package.
COMBINED SHIPPING: I'm happy to combine shipping on multiple purchases. Those shipping within the US will combine automatically. International orders must be manually combined after the purchase, and any excess shipping will be refunded to your payment source (due to the way eBay buy-it-now items are set up, this is the only way I can combine shipping on more than one item).
HANDLING TIME: My handling time is one business day and eBay requires me to ship within that timeframe. I cannot withhold shipment for a later date. If you require shipment on a specific date I can often set up a special listing just for you on that date; please inquire.
I usually ship every day of the week, except for Sunday and USPS-observed holidays, and orders often ship same day. Orders placed later in the day usually ship next business day. Orders placed on Friday or Saturday will sometimes not ship until Monday. All orders placed on Sunday or USPS-observed holidays ship the next business day.
Expedited and express shipments (FedEx and UPS 2-day & Next Day, etc) must be placed by 12PM Pacific Time in order to ship same day.
If you have an urgent delivery need it's a good idea to contact me first so I can confirm exact day of shipment.
SHIP-TO ADDRESS: Ebay requires that I ship to the address on the order. This protects both you and me. I cannot ship to a different address. If you require shipment to a different address please update your shipping information before making a purchase.
