Description
GE/RCA 7581A Tube Tested @ 6L6 Specifications - Drop-In 6L6 Replacement See Photos for test results. Tested at operating points from tube manual specs. Curves Plotted @ 400Vp 300Vs Tested @ 250Vp 250Vs -14Vg (Tested as 6L6)35W Vs 6L6 30W 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 FedEX shipping services. Please contact us for special shipping needs. Ask any questions are concerns you have prior to purchasing so your transaction can be fast and accurate!

Buyer to add $6. shipping USA, $16. WORLDWIDE PLEASE READ: I use either a calibrated Hickok 539C, TV-7D/U, or for new design tubes a calibrated B&K 747. Test results must exceed the tester minimums by at least 10%. I attempt to match all the tubes sold in pairs to within 7% of the test readings. Because I dont know the operating condition of your equipment, tubes are sold as is. I may have several of the tubes being auctioned, and may NOT use a photo of the actual tube. There may be some larger type tubes that I do not have the equipment to test for other than filament continuity (Ill put that in the listing).INTERNATIONAL BIDDERS: Because I can only test for technical things like transconductance, gas, shorts, etc., I cannot test for things you might think you dont like (tone, response, etc.). UNDER ALL CIRCUMSTANCES: if you purchase any tubes YOU agree to be responsible for any return postage. QUESTIONS? please ask them before bidding. PAYMENT INFORMATION: You can either use the PAY NOW button at the end of the auction, or Ill send you an invoice. I try to ship most items within 2 business days of payment. eBay NOW REQUIRES A SIGNATURE UPON DELIVERY FOR ALL SHIPMENTS OVER $750.. INTERNATIONAL BIDDERS: I accept payments from International Bidders for amounts up to $250. For larger amounts, contact me. TEST Powered by SixBits eCommerce Solution

Description
I have for sale 3 x 7581A KT66 tubes. All are the desired GEC double halo getter versions. All test very strong as new On AVO MKIV new tube tests 70ma - these test 70,69,85 tight bases - last ones of this batch I have Tube Testing: Unless stated new old stock all tubes are used. I test all tubes for shorts, filament and emission. All my testers including AVO MK IV , Lafayette etc are vintage, and I have not had them calibrated in decades. For this reason I no longer list the emission readings of tubes as they would not be precise. The AVO MK IV still to this day is regarded as one of the best tube testers ever made. I personally think the AVO MKIV is the best for testing most tubes with the exceptions of 12ax7 and ECC88 etc which I feel the results are accurate but not precise. I only list good testing tubes and have been around tubes for many years and as always stand by every tube I sell and have excellent feedback I PACK ALL TUBES VERY WELL FOR SAFE TRAVEL AS REFLECTED IN FEEDBACK.No longer post to China as I will not declare lower value for customs as it is illegal to do soUnless stated New Old Stock all tubes are used I NO LONGER POST ITEMS TO ITALY, GREECE, RUSSIA , MEXICO ETC DUE TO POSTAGE DELAYS For buyers in Europe and parts of Asia that have high import duties, please remember I do not falsify customs forms so please be aware of your own regulations.
