DIODES ID

Top ones are germanium diodes, they've got arsenic inside them so be a bit careful with them. If you can get a multimeter with a diode setting in it you can check the forward voltage, that should give you a bit more information to get a pisitive ID ob them.

They might be 1N4914 silicon though, they're quite a common zener diode.

I've got some old Germanium diodes that look a lot like the top photo, and I've used a couple of them in a Superfuzz clone. They work well as clipping diodes in pedals, as they seem to clip in a softer way than silicone diodes, though you end up with lower output due to the lower forward voltage. Also, I wonder if the ones with the 91 might be OA91?

never used the Diode bit of the Meter before (only for as continuity testing on some meters)
2nd Diode with the 914 has a reading of 840-837 dont know what that means personaly
<ive got a Transistor part on my meter too>
I looked up the IN914 and some photos and this is the sidewards 4 marking i have on mine


----------
The Germamium ones have a reading of 365, and i think it is a Germamium,
i was reading about Fuzz Pedals at one point and do recall wanting some of these

Top ones will be generic OA90s, OA91s, or something similar, tbh in practice a germanium diode, was agermanium diode. Even Mullard OA91s used to vary quite a bit anyway, so I'd just treat them as that. if your using pairs, try and match the forward resistances.

The others wil be 1N914 as has already been said, similar to 1N4148s.
