Title: Laney Amp - 220V to 120V
Post by: Joe6v6 on January 21, 2026, 06:48:46 pm

Can anyone see what needs to be done to wire this for 120 volt operation? Its set at 220v now as it came from the other side of the pond. The Brown & Blue wires go to the 4 prong switch.  .   Thanks for any info.  .   Joe

Remove the jumper between 0 and 120. Put a jumper between 0 and 0. Put a second jumper between 120 and 120.
