If you seek tubes that are tested at tube manual specifications, please consider clicking the Save This Seller link at the top of the page. See our feedback. Thank you. We guarantee and test all our vacuum tubes based on the manufacturers tube Manual specifications using uTracer3+ curve tracer & Tube tester, regulated DC and AC power sources, benchtop and handheld multimeters for accurate precise repeatable measurements. I love my TV-7B, Hickok 800, 6000A, EICO 667, and my B&K 700. But these are just tube testers and not true parametric testing equipment. They are for Go - No Go testing and are best for weeding out bad and weak tubes. Truthfully, the best way to know how a tube will work is to use it in the actual application. The next best thing is to test it at the manufacturers parameters in the tube manual with proper lab or bench testing. This way one knows how close the tube is to its designed standards. This may seem excessive, but we try to offer the tube amp builder, technician, and musician the best service and product we can. More tubes to come.

Svetlana Winged C 6E5C Magic Eye Vacuum TubeFrom the inventory of a long closed electronics shopNew old stockThese tubes date from about 1963 The logos and marking nomenclature may be different from tube to tubeBut these are all Svetlana Winged C tubes Some tubes are marked on the base instead of on the glassSome only have date codes but the date code is in a unique style and is the same on all the tubesI suspect that at times the quality control was not as good hence each tube looking slightly different Please note that these are NOT a direct replacement for the American 6E5 tube, these have a completely different pinoutI do not know if you could use these as a direct replacement for the 6E5C, but if you could it would probably involve rewiring to an adapter for the correct pinout This tube uses an 8-pin octal baseData sheets can be readily found for this tube online I have sold hundreds of vacuum tubes over the last 11 years and I always get positive feedbackMy vacuum tubes are always accurately tested and honestly describedPurchase with confidenceMultiple quantities availableIf you purchase more than one, I will combine shipping and refund the differenceWill be carefully packaged for safe shippingWill ship via First Class Mail

Svetlana EL 34 Winged C Valves/Tubes Matched Quad. Purchased Feb 23 from Hotrox who sell at best price. Now £70 each valve. These have had around 30 ish hours on them but I have sold the amp on with original valves so not needed. Selling at almost half price and I will include post UK only. Not easy to find. Some of the print on the glass has got rubbed off see pics. Not detrimental. These are considered one of the best EL34.

Heres one of those rather good Svetlana black winged C EF86 that we import from Ukraine. Well you gotta help out, eh?This one is in very good condition. Its testing quite strong on the AVO with emission figures of 165% and a gm figure of 117%...which is certainly a muscle tube, as my tekky puts it.We give these EF86 types a good burn-in before even testing them to eliminate the brand new microphonics that occasionally plague them when brand spanking new. As this burn-in occurs in a spare Mullard 5-20 amplifier we can listen to it for quality of audio improvement over the first 24 hours or so.......These arrive bulk packed by my supplier in Kyiv (i.e. no boxes...) so we put em in quality white card individual shipping cartons. All details are on the box.Please note: we retest every valve before dispatch and check for microphony. If any valve is still lively because of this slight microphony, well post a better/better behaved one......
