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.
