I don't understand the question since all of the tie points are labeled on the printed circuit layout and referenced on the drawing.

 

Out = Speaker Positive
2 = Speaker Negative
In = Signal Positive
1 = Signal Negative
+ = Positive Supply
- = Negative Supply

 

Out = Speaker Positive
2 = Speaker Negative
In = Signal Positive
1 = Signal Negative
+ = Positive Supply
- = Negative Supply

Thanks mate, your a life saver

 

Where's the Supply GND ?

Tie point #1, common to tie point #2

sorry i'm confused could you please explain to me what you mean by tiening these points

 

I hope this helps

A tie point is a place where two or more circuits or wires tie together. Those points (places) are identified on the circuit layout.

odinhg has done a great job with his visual representation. As you can see, the points (connections) he tied colored lines to have numbers to identify the tie points. The gray are between point #1 and point #2 indicate that these two points are connected together or "tied" together.

 

I hope this helps

what is the supply common, 0v

 

A GND or 0V is the supply common point.

Positive and Negative supply with respect to GND.

The common point of the two smoothing caps that is connected across the bridge.

The center tap of the transformer

sorry im still confused, could you perhaps tell me if anything extra needs to to be wired there or is it just a point to take , not and remeber

 

Hello,

I have combined the picture of the powersupply from your given website with the connection diagram odinhg gave:

I hope this will help you.

sorry but i have been even more confuesed now, can you just tell me what is meant to be wired their as i sometimes get a little bamboozeled by certain schematics, kind regards, mu71b

 

do i just link the negative from the battery with that grey wire, ???

 

Hello,

When you are using batteries, you will need two of them.
Connect the + from the first battery to the - from the second battery.
This will be the grey wire.
The + from the second battery will go to the red wire.
The - from the first battery will go to the blue wire.

actually, thanks, you solved , it
