ECC82 12AU7 Siemens long plate, D-getter, tests NOS+, 1956 Munich

Siemens ECC82/12AU7 with 45 degree D-getter and long plates, made by Siemens Munich. The tube is branded „Elektron“ but the code clearly identifies it at Siemens Munich production. Elektron was a reseller brand for surplus stock.

Code on tube is =6E (= Munich, 1956, May). This tube may have seen minor use. It tests perfectly, very balanced and still better than new (100%+ emission).  This version is among the best Siemens ever produced! Super rare and sought after version.
