General Electric Tungar 4B27 circa 1932

The 1932 Tungar 4B27 presents spatial cues with an amazing openness and transparency- sound seems to emanate in concentric circles from image points with ghost like transparency. Air and sound staging dramatically exceed the boundaries of even the largest listening rooms while highs take on an effortless crystalline clarity. This tube extracts the essence of recordings in a way only matched by Japan's most exotic (and expensive) hand built electronics. It's as if you are listening through $150,000 Japanese SET mono blocks with hand wound pure silver transformers and rare NOS tubes. Coupled to high current solid-state electronics you hear the perfect blend of power and purity. When paired with tube electronics, music is elevated to the highest expression of valve technology. With it's immense portrayal of space, the 4B27 Tungar is best suited to large scale ambient recordings. Perfect for classical orchestras, electronica, or any recording intended to portray a large sound field; you hear space as it was recorded for the first time. Given the ultra rare supply of these tubes, only one hundred and twenty five Enigma LE's will be built with the remaining stock of tubes held in reserve.

Engineered for utility
Manufactured as a high current, low voltage rectifier for battery charging stations, the 1932 Tungar 4B27 is uniquely qualified in it's current role as a 30 volt DC rectifier for Tesla Active Shielding. As a rectifier for charging batteries the Tungar was expected to work night and day at high current. In the Enigma it operates at less then 5% of It's rated output and can be expected to power Active Shielding for 20,000 to 30,000 hours or more. First developed in 1916 and in production between 1919 and 1949, this tube was in use in gas stations during the Great Depression and as a mainstay for charging lead acid batteries during WWII. Packaged in their original wrapping and with their original warrantee cards, the Tungar tube was “manufactured under supervision of men who were instrumental at the General Electric laboratories during the Tungar's development in 1916.” -quoted from the Tungar 4B27's original warranty card included in it's original packadging with each Enigma LE.
