Considered the HOLY-GRAIL of the Siemens & Halske Munich West Germany tubes. This is the rerest "Long-Plate" 2-getter support audio tubes ever made, with fast response, overwhelming detail, the most realistic bass, and overall perfection in a 12AX7 / ECC83 class of tubes. The most rare of the West German Long Plates!
Rare. Great. Made only from from 1959 to 1960.
