Help with Constrictor Opto orientation and gain break out pot.

[ac30irons]

Hi all, first post.

Can anyone help with which way the Optoisolator goes on ? I have attached a pic of how I think it goes (the long leg is top left of the Opto) which would suggest it’s the anode yet I’m sure I can see a little + on the other side (bottom left short leg.)

I would also be really keen to know how you can break out the gain trim so it’s on a pot !

Thanks in advance

Please see pic.

The way mine turned out was with the vactrol label underneath, if that makes sense. Try to ensure that the long leg matches the + sign. If in doubt, socket it so you can change as necessary.

Give me a couple of minutes to confirm the trimmer to pot wiring.
