Degenerator - NSL32R3 - install check

[jessenator]

Just wanted to confirm the install for the NSL opto part before I put iron to solder.




Just want to make sure I've got it right: I have the "dot" on the part on the same side as the dot (opposite the "+") on the board. then the second set of contact leads just loop right back around to the other set of pads, correct?

Yes, the dots should be aligned so it looks like you have it right. The dot shows the location of the cathode side of the internal LED.

Thanks, Bean!

Now that I've woken up are you sure the dot isn't on the other side of your NSL? I just checked on mine and they are on the right side of the lettering. Also, look at my build pic and notice the lettering imprinted on the top. Opposite of yours.

Unless there was a manufacturing problem? Now I'm paranoid about installing it lol. There's a silver blob

Oh, okay. No, you were right the first time. You good.

I've pooched a few of these so I feel your apprehension.

Yep me too, every time.

One way you can check is to use a breadboard. Use a 1k resistor to power, next the first pin of the vactrol  and the second pin to an extra LED in series then tie that LED to ground. If the second LED lights up you have the correct orientation.
