This is why we can't crank out 6 new modules/month.

I've never done this in my whole life.

I bought 500 because they are custom made, and so they will turn up on other
stuff.

That's ∗my∗ $6, your $15 (kids gotta eat). (the astute will realize I got
$3000 worth of LEDs.)

The assembled ones are defaulted to SINE as well, but some days I like
PULSE.

I agree and may change the panels when I run out to add NEG....0....POS
labels
or something like that.

On another note, it was suggested that I change to ∗threaded∗ spacers, to
you don't
have to juggle with them rolling around when trying to stick the screws
through the pc board.
I will do this in the future (of course, I have about 1200 plain ones. Maybe
I can sell them to Barlow....)

This is not all that critical, but the point is don't press the 2
transistors in ∗as far∗ as the other ones.
But not so long as to have them on top of the beast!

You told me 6 originally :( {just kidding}
