You are bidding for one pair Telefunken AL4 Mesh Black Plates Tray Getter Tested NOS Matched Pair Price made in Germany in the 1940s. The tubes were tested on AVO CT160 at the NOS range. They are substituted for 6V6 with amazing sounding quality. They surpass all versions of 6V6 types in the history. They are deserve a try and worth every penny I must say. If you want adapter sockets, let me know so that we can DIY for you to plug and play directly into 6V6 position. Super rare and hard to find now. The tube doesn’t come with a Telefunken box. Return is accepted if you pay for the returning fees. Selling as is. Please ask me any questions before buying. Thanks
