old diodes

[Stevebol]

I'm looking for a diode from an Advent 100 and it seems to be outdated. Not sure what specs to look for for a replacement. This is the best info I could find. It's a IN191.

Is the diode shorted or open?

Germanium

Appears to be an old germanium diode.
On Semi doesn't cross it but NTE crosses to a NTE109

NOTE: I am not a qualified tech. I just used the cross references that I know of. You should check the specs.

Maybe a tech will point you in a better direction.

No. I've just been taking readings on two identical boards and one diode measures different that the other. There's a difference in output volume between the two boards. I replaced the electrolytics. I have two of the Advents and two of the playback boards are the same in each. After swapping the four boards around I narrowed in down to which one is the problem.
I'm pretty much a noob at troubleshooting with a multimeter. I'm done recapping the other unit and the Elnas sound nice.
The diode in question is a germanium I think. Small, glass.

Thanks for all the info. I have some reading to do now.
