curcuit board

Use brass machine screws installed from the rear of the board with nuts on the front, Replace them all you will never fix it again. Get them at a Fasten-al store or a good electrical hardware. I have also uses stainless Allen button heads. The threads also make a better contact.

Just some advice for all. I hope this don't ruin the sale for who makes them but some of us enjoy fixing things our self and are short on funds.
