4682 (Philips Miniwatt) = AL2/375. In the original box. Parameters as follows: for Uf = 4V, Ua = 250V, Ug1 = -25V and Ug2 = 250V, Ia = 33mA (100% Ia = 36mA). S(lope) = 2.5mA/V (versus 2.6mA/V in the catalogue). In other words, more than 90% of nominal emission, good and sensitive tube. Really pretty. Tested on ELPO P-508 tube tester.
