>variation in Vf normal in Ge diodes..?
Vf is often poorly specified (like < 1V @ 5mA), but may not vary that much within the same lot. Are your diodes marked or just glass? I have no 1N34 but some other AA.. types. The six AA144 from the same tape I checked had 255±3 mV at about 1mA. For comparison: BAT43 250 mV, 1N5819 200 mV, 1N5817 160 mV, AA135 190 mV, AC152 B=C ≈100mV, all at about 1mA.
