Troubleshooting guide:
Symptom: No audio, tubes and front panel LED don’t light.
Confirm that the AC power cord is firmly connected at both ends.
If the amplifier is plugged into a power strip or a power conditioner, confirm that the power switch is
on.
Use a lamp or other small electrical device to confirm that there is AC power at the outlet. If the
lamp does not light, check the fuse box or circuit breaker.
Remove the power cord from the amplifier, open the fuse holder, and inspect the fuse. If it has
blown, replace it with the spare. If the fuse blows again, contact your dealer or Red Rose Music’s
customer service department.
Symptom: No audio, tubes and LED light
Make sure the Power switch is not set to STBY.
Make sure the program source is turned on and producing a signal. Confirm that the cables from the
source component to the amplifier are connected at both ends.
Confirm that the speaker cables are connected to the amplifier and the speakers.
Use the BIAS MONITOR switch to check the plate current of the four output tubes. If the meter
shows low plate current for one or more tubes, and you are unable to use the Bias Adjust control to
bring the plate current up to the correct value, replace all four output tubes.
If the meter shows no plate current for a single tube, or if the red LED in one of the output tube
sockets lights, disconnect power to the amplifier and replace the fuse for that tube socket.
