Svetlana Winged C EL34 6CA7 Tube • Class A Tested • 02 SEE ITEM SPECIFICS FOR TEST RESULTS. Other Single Tubes available To Match To this One. Solid Tube. See The Test results! *Tested @ Tube Manual Class A Parameters Thanks for visiting our store! See photos for tube cosmetic condition. 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. Shipping The tube/s will be packaged in original box (if applicable) and then sent out in a 6x4x4 shipping box. We use USPS or UPS shipping services. Please contact us for special shipping needs. Ask any questions or concerns you have prior to purchasing so your transaction can be fast and accurate!

EL34 Svetlana Genuine Winged C Matched Pair Valves Power Tubes, Fully Working. Previously NOS Russian-made EL34 Svetlana tubes, fitted to a Marshall head. Used, occasionally, but the head needed re-capping, so the valves are being moved along in the meanwhile. Fully working, strong power tubes that were biased right down the middle when in use. Great matched pair for some genuine power section breakup and thickness. Due to constant issues with Evri and DPD, and non-existent support and customer service, this will be sent with UPS. It will be packaged carefully if you choose to receive it by courier, although be aware that this is always an extra risk, especially with hard to replace, vintage equipment. For this reason, proper air gaps and redundant shock absorption will be used in packaging, with as much recycled materials as possible (bulk-bought reused bubble wrap, waste paper and card stock, reused polystyrene etc) to help save the world just a tiny bit. Tracking numbers are automatically uploaded to eBay upon booking, and are usually trackable right to your door. Dispatch time can vary, with work and family commitments, but generally ASAP means within a day or two. If you have any questions at all, queries, requests, or dad jokes, please feel free to get in touch.
