Thanks. Here is another photo of the wiring. By the way I will not attempt this myself, I will get an electrician to do it but I just want to learn.
Also, the colours don't match up to the wiring. My friend (an electrician) has taken this amp apart before and I remember him saying the wires aren't matching up to the same colour, it was just a guessing game for him. Just wondering if anyone knew what it is, as he has moved away. Cheers
Something odd going on as there is no connection from "Live" to any of the other points when the switch is on. Is that fuse OK ? Measure across it on ohms, it should read short circuit (0.00)
Neutral and A and B appear connected... that's as expected and means the switch is a single pole type switching only live. On the first block of readings I missed out F... an ommision, not intentional but assume it reads open (1)
This is how I would imagine it to appear... in black is the connections you have established... in red is what I would expect with the switch feeding one or more of the other connections. So check the fuse first.
A bright torch shone under the PCB might reveal the patterns too.
The connections are as I thought then, however normal good practice is to switch the LIVE side of the incoming mains, and for that to go through the fuse FIRST. That's standard safe practice.
You said at the start that your friend said the colours don't match.
I would expect the BLUE wire from the tranny to go to the neutral of the incoming supply and the BROWN to go to the PCB... yours seems the other way around.
That's not a safety problem in itself as the transformer is "non polarised" and normally the wires from a transformer aren't colour coded anyway.
Can you confirm that with the mains switch turned ON that there is continuity from the glass fuse (both ends) through the switch to one of the connectors on the PCB. Your readings up to now indicate NO continuity... so we need to find out why. Where does the other side of the switch go ?
Up to now (from the photos) it looks as though the BROWN wire from the transformer goes to the mains inlet socket directly... is that correct ?
The other terminal from the mains inlet goes to LIVE on the PCB.
So that leaves the BLUE wire from the tranny which needs to connect to the switch to complete the circuit.
And it's the continuity through the switch we haven't established yet.
I would say the BLUE lead connects to the lower right tab in the piccys and that the amp should work then.
Just if your wondering... there's no safety problem in all this... it's a very simple circuit switching one side of the mains only... the only mystery is why you can not read continuity through the switch when it's on.
indeed AC in OZ was 240, but is supposed to be now 230 to bring it more inline with the EU etc, many places still have 240 though regardless of what the switches say. brown is normally live here and we generally have a 3 pole 'balanced' power scheme of live/neutral/earth though plenty of more consumer grade audio gear is only 2 pole. its possible the 240 vs 230vac thing had him confused...hey OP?? hehe
for sure take a picture next time, dont worry i'm pretty sure we've all done it, I know I have
