Title: Diode casing cracked
Post by: Natibah on October 11, 2020, 02:09:10 PM
Hello All,
I was putting together a pedal kit and one of the diode casings cracked. I figured it should still function, but once the pedal was together, the octave part of the pedal doesn't seem to do anything except light up an LED. The octave part routed through that diode, so I was thinking that it is the problem.

It is the D2 diode on that wiring diagram. Would a cracked diode casing result in no effect from the second footswitch (Sw2)?
Thanks!

Quite possibly the diode is dead. But they're cheap enough to replace :)

If you ask in the Parts Jar subforum, someone in your country might have a spare.

I have extras. I dread trying to remove the one that is in there and replacing it.
Thanks.

If you gently clip the leads of the diode first, it's often easier to remove the leftover ends after that.

Ha! funny you should mention this. I think I broke about 3 Ge diodes in 10 minutes yesterday just trying to put them into PCBS. Never had such bad luck...

Yeah, I had it soldered in but one end was higher then the other, so I decided to soften the solder and push that in a bit to even it out and it cracked. :(

Usually I do this with small fragile glass housing diodes. I use a little screwdriver as guide, and wind the leads on it.

They take more space, but I'm no longer a diode destroyer!

Interesting. It was a glass housing diode. I will give it a shot.
Thanks.

I'll have to give that a try, that does seem like a good option!

For some reason I've always been concerned with having a exposed leads, which is why I've steered clear of vertical resistors (orthogonal to the pcb?). But if a small amount of exposed lead doesn't matter, I may try and vertically/orthogonally orient some diodes, since it might be easy to clamp part of the lead while bending the remainder.

testing testing testing...
