E180F / 6688 NOS-NIB, gold pin, various German brands.
beautiful small tube with gold pins
most stock is Siemens / VALVO / SEL and SEALED ARMY PACKAGES
(these may contain any brand but most likely the same as the boxed brands as they are from same army surplus stock) they are sold in white boxes
recommended upgrade for the 6j9p as in the Nobsound NS-08E
Note: there are two versions of the NS-08E, only one uses 6j9p (9-pin) tubes, the other uses the 6j3p (7-pin) tubes.
