I'm installing a new speaker in a WEM Westminster and I see that the speaker terminals are marked + and -. I had assumed that as there were 2 wires, which went where wouldn't be an issue but perhaps not.
The original wiring has been replaced with domestic lighting wire (blue and brown). Can anyone tell me from this pic of the circuit board which is the +ive wire? See extreme right of pic for where they exit the output transformer(?). I'm thinking brown is +ive but I'm not certain and don't know if incorrect location would damage anything. Thanks.

Logic would dictate that the brown wire is +ve but connecting to a single speaker it matters not.
If you are connecting two or more speakers together they need to be "in phase" but even here, if you get it wrong you will just get a weak sound with little bass, no harm will come to amp or speakers.

VERY good point D! One side of the transformer secondary MUST b connected to chassis. It is very, very rare for a primary to short to secondary but it can happen. Tied to chassis a fuse will blow.
