Here's another one from the back of an old amp.
Do you recognize the ground plug and AC outlets?

Hi Nicole,
I think I understand the confusion now. Here in North America, these units were supplied with a two wire AC plug. That's why this is confusing to us over here.

The addition of the third ground connection may be law where you are. That is why one of our members from your area should speak to this.

Your fault sounds like the wire has broken just behind the AC plug boot, replacement of the plug would be the correct fix. It must be done in accordance with the laws in your area.

If the amp has one of these then it is not US Spec. At the time of this amp, it was against the rules to ship a unit that had any switchable mains capability to the extent that mass market items like this amp had a North American only power trafo with only a 115V primary.

Pls. try to take a picture of the back of your unit and the wirings
so it will be easy for everybody. Its kinda difficult to give you
information if we cannot see part of your unit.
I think everybody here is willing to help, but they are not much
familiar in electrical code there in your country.

This simply indicates a broken wire or bad contact near or inside the mains plug as posted above.
You got it right in thinking that the plug you recognized is not likely the original.
In origin, the amp has only two wires and the plug has three pins.
In the past, someone connected a third wire (which was never there) from the plug to the chassis of the amplifier.
This chassis connection or ground therminal(s) are for turntable(s) as many of them need it connected to prevent hum.

Do yourself a favor and take your amp to someone who can fix this, i.e. a local electricity shop. If you're lucky they will fix it instantly and you will learn the most out of looking how they do it and asking a few questions.

The AC outlets on the back are there to provide current to other equipment connected to this amplifier, meaning that the other equipment needs to have a plug that fits in the outlets.
'Switched' will switch on the connected equipment when you switch on the main amp. 'Unswitched' means that the outlet always carries 240V when your amp is connected to the mains.
Don't stick anything in there.

Default pioneer amp

hi hugo,
yes thats what i was thinking...well took that silly piece of wire out which was goin from the t/tables ground to the ac and i will cut the wire down later and see if this solves the dodgy connection.
thanks have been a help to me ,,,just so i can clarify things ,,,,and can probably fix this myself provided it is just a broken wire inside the mains lead....cheers....
will try it tonight.
