I’ve got a DPDT board populated with 4 – 1N4148s on one side and 3 D9s on the other. How do I connect the wires from the DPDT to the main board?

When I initially boxed this OKF and Emerald Ring the signal cut out when I engaged the Ring and it didn’t work on its own. Thinking I had damaged the Ring removing it from one box and installing it in another I ordered another.

OKF with Tight Switch and an Emerald Ring.

If you socket the modifications and the mods don’t work it will be easier to undo them and make it work as originally intended or mod the mods to get something you like.

Above 50% they will boost the signal which would give the impression of too much gain. The clipping LEDs tend to be louder than other diodes so maybe replacing them with 1N914s or 1N4148s would drop it some.
