Glass diodes

[O]

I found these in an old mixer and I need to know how to "decode" the value. I found a site online, but it didn't make any sense. Can someone tell me how to find out what I have?

These are the colors...
Yellow, Green, Blue, Violet

(I also found some tropical fish caps and various transistors, but I don't think I can use those.)

Thanks!

Somewhere around here it tels typical diode foreward voltage thresholds. I know the data sheets have that. Look up
 1n914 [not also it's an Si]
 1n34  Ge.
 Ge's are lower foreward threshold something like .6v - .7v,  you can check this with DMM's diode mode, invert the diode if no reading appears, when reading appears not which side of the diode goes to black.
 Test future FVT of diodes, match or mismatch for symmetry or assymetry when used back to back for clipping or other uses.
 I have some sorta big clear glass 1n34's others I have are blue.

Nah, you don't need those... better give them to me...  :mrgreen:

In all my born days, I never saw a striped diode.. but, when I typed
diode color chart
into google, the above link showed up :wink: Enjoy!

That'd be a 1N-456G diode. That site is real nice....bookmarked. In terms of a datasheet:

Hope that helps,

P.S. couldn't find the datasheet for the "g" model...that's the "a"

mmmmm tropical fish....

my fav tone caps.

Thanks for the replies everyone. Paul, that's the exact site I went to (I just couldn't make heads or tails out of it).

About the tropical caps, I'm going to test them first to see if they even work (the mixer they came out of is from 1968)
