Question about Music
I have just bought and amplifier but the front switch is faulty. there are 4 wires going into the switch: brown and blue from the mains and red and black going to the transformer if i was to bypass the switch what colours would i need to join? i know that blue is neautral and brown is live but am unsure what the black and red are??
Get an ohm meter and test to a known ground, like the sleeve on the guitar cable. If neither is grounded, it doesn't matter. If one is grounded, take it to neutral.
Best bet, get the same switch and put it in exactly like the one you have.
