Hi,

On this schem, are the points marked "9V" (three total), all points at which you bring in raw voltage? You would basically have 3 "board" 9v points?

I've just never seen that before, I'm used to just 1!

am I correct?

thanks guys!

I would say yes.

Just like with ground, all the points named "+9V" must be wired together. One board entry will be fine.

In electronics industry practice, schematics can be drawn in ways that show the function clearly, or completely. It's sometimes hard to do both at the same time, even though that is the idea. For instance, nets that connect to a high fraction of the parts on the board can be very obscuring, filling up the schematic with essentially information-free lines. Ground is the best example; it connects to a whole lot of components, and it's very, very hard to draw the ground "wires" in a way that shows exactly how the ground should be hooked up. Other nets that have this characteristic to some degree or other are the power supply or supplies, and any bias voltages.

It's become common to merely label such nets with a symbol, like the down triangle for ground, circled "+" for +power supply, circled "-" for negative power, or just an acronym, like "+9V". All that means is that all these points are to be connected by copper traces or wires.

R.G. How much would I have to pay you to come over and watch TV, I'll work in back, and whenever I have a question I'll just come in and ask you?

thanks as always...
