Wouldn't you rather see the test results of a tube you are considering buying instead of taking a total stranger's word for it? This early 1960's GE 12AX7A with 14mm ribbed gray plates and a halo getter has passed testing for gas, shorts and mutual conductance on our newly calibrated Hickok Model 799 Dynamic Mutual Conductance Tube Tester. Photos of the actual testing of the two triodes of this specific tube have been supplied. On this model of tube tester, 54 is minimum good (65% of new). Theoretical "new" is a range defined by one standard deviation on either side of 83, from the low 70's to the low 90's. As you can see, this tube tested a NEAR NOS PERFECTLY MATCHED 67/67. Averaging those numbers, one can estimate that this tube has over 80% of its life left, in other words, THOUSANDS of hours. The printing is good (in white) GE logo Electronic 12AX7 ECC83 188-? REFUND POLICY -- PLEASE READ THE FOLLOWING CAREFULLY No returns are allowed. This tube is sold as is. There is one exception to this rule. We guarantee that what you see is what you get, and if you carry out testing on this tube, the results, if obtained from properly calibrated equipment, will not be materially different from those that we obtained from testing it on our newly calibrated Hickok Mustang Model 799. This specific tube passed tests for gas and shorts, and the results of the actual testing of its triodes are documented in the photos that we have posted on this listing. If the tube you receive from us yields documented test results on a properly calibrated tester that are significantly different from those advertised by us in the listing, please inform us immediately. In order to qualify for a refund, the buyer must pay return shipping and must return the tube packed in its original materials to us within seven (7) days of receiving it. After re-checking, we will either replace it with a closely comparable tube (if possible) or refund the buyer's money immediately. We do not accept the return of any tube that has been damaged by the buyer -- cosmetically, electronically or in any other way. Tubes blown through use on a broken amplifier are not returnable. The buyer should be careful not to rub off any of the old and sometimes powdery, silk-screened printing on the glass surface of the tube. Tubes are graded in part on the basis of how much of the original printing remains on the tube and losses significantly damage the tube's resale value. Damaging the printing also renders it impossible to identify the tube as the same one that we sent to you, thereby voiding our guarantee. Our tubes have also been stamped with a logo in a water-soluble ink. The buyer should be careful not to remove this logo during the seven-day grace period. If the ink logo is rubbed off, the tube can no longer be identified as having come from this store and thus it cannot be returned. We keep a set of close-up photos of each tube. We do not guarantee that you will like the sound of this tube in your application. We are very confident based on past experience that you will, but we cannot guarantee it. Not liking the sound is not an acceptable reason for a refund or exchange. PAYMENT Payment is due immediately upon purchase. We accept Paypal from confirmed addresses only. No exceptions. SHIPPING Next day shipping to addresses in the United States is $3.99 USPS including insurance and delivery confirmation. If you object to this charge please do not purchase the tube. I also ship to Canada, the UK, all EU countries except Italy and Greece, Australia, Japan and Hong Kong by US Global Express Mail. The package weighs approximately 115 grams. Packages shipped abroad must be trackable, insured and signed-for. I will not ship to any other countries, please don't ask. To international buyers: Customs in your country may levy various fees and charges on this package which the buyer is responsible for paying. Please also note that Ebay does not allow buyers to ask sellers to falsify the va... read more
