Lightly used, Like New, Single Tubes Rare 1958-60 Mullard E88CC Wrinkle Glass Halo Getter type. 1958-60 7L0 and 7L1 Revision with Mitcham or Whyteleafe plant date codes. British Made.
7L0 is one of the earliest revision from late 1950s and these Halo getter E88CC tubes are obscure, and more desirable than the later production with Dimple Disk getter. Very clean glass. Labels are fragile and not perfect as expected from tubes of that era. One of the best Mullard made E88CC type tubes. In white boxes from bulk.
