USED Matched Pairs 1960s Amperex/Philips ECC82 HALO Getter Tubes with various Labels like Adzam, Philips, Philips Miniwatt, Valvo, Pope, Dario and Siemens & Halske etc. Heerlen Holland Production Date Codes on all tubes (first letter 4xxxx, 4=delta or left triangle for Heerlen Plant). Repacked in white boxes from bulk. One of the most musical and desirable tubes in the 12AU7/ECC82 family. Labels are a bit fragile and not perfect as expected from tubes from that era and tube glass shows varying degree of use.
*Heerlen plant tubes were sold with different labels like Amperex, Miniwatt, Philips, Bugle Boy and also relabeled by various Philips associates or companies owned by Philips like Valvo, Mullard, La Radiotechnique RTC, Siemens, Adzam etc. Etched date codes tells the origin of the tube.
