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 don't 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 (I'll 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 don't 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 I'll 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 SixBit's eCommerce Solution
