Voltage Selection:
• Unplug the unit! Open the unit and locate the jumper switch, on the power amp section to the rear of the
unit. Change the jumper over as illustrated in the photo above. Make sure the switch on the rear of the
unit also has the correct voltage selected.
Troubleshooting:
• No Sound :
Check cables & connections. Check to ensure there is no short on the speaker cable. If light is off,
check the fuse on the power amp (Unplug before doing so). If still no sound, check to see if the preamp outputs
operate. If everything is dead, try replacing the 12AX7 tube.
• Overheating/No Sound :
If unit is shutting off and is extremely hot. Try opening the unit and cleaning with
compressed air. The overheated power amp will reset within a minute.
• Scratchy/Microphonic Sound:
Try replacing the 12AX7 tube.
