Sourced from Ukraine, these are New Old Stock (N.O.S.) Soviet D9K (Д9K) Germanium Diodes. We measured 10 pieces of these on a Peak Atlas DCA55, and the forward voltage on these seems to be fairly consistent, from ~.39 - .45, with 6 of the 10 pieces being exactly .41. These make a fine replacement for the 1N34A diode, and these are more consistent than the new production 1N34A Germanium diodes we stock.
IMPORTANT: The red line on the glass marks the ANODE, which is the opposite of the line on the cathode as is typical of most diodes.
