Help Sourcing A Part

[GUARBorg]

I have a couple through hole diodes I haven't been able to source. Does anyone know of a good site or database I can check to decipher the case markings? I have plenty of sites for SMD parts but nothing devoted to obsolete through hole components.

First is a orange/black glass sealed diode (probably a zener) with a case code of 135.

The second is a standard looking diode with either "9H" or "H6" with a vertical "37"

These parts are 10-15 years old if it helps.

If we can see the good pictures of the board to see how that diode is connected in the circuit then we may be able to determine its function.

You might be interested in getting a sub $20 ebay component tester.

I bought one and have used it a few times and I love it.
