TROUBLESHOOTING GUIDE
SPECIFICATIONS
WON’T TURN ON
1. Make sure AC cord is securely connected at
both ends.
2. Verify the power source with something you
know works.
3. Check the mains fuse, and replace if necessary.
If it blows again, refer to qualified service personnel.
NO SOUND
1. Check input cable.
2. Check volume controls.
3. Make sure the amplifier volume and/or gain
controls are turned up.
4. Check to see if the effects loop is connected
correctly.
5. Check speaker cable to see if it is disconnected
or shorted.
6. Make sure that the impedance selector is fully
engaged in its detent.
7. Check the standby switch.
8. Check for a blown speaker.
9. Check the mains fuse, and replace if necessary.
If it blows again, refer to qualified service personnel.
WON’T SWITCH TO OPERATE
1. Check the mains fuse, and replace if neces-
sary. If it blows again, refer to qualified service
personnel.
EFFECTS NOT OPERATING
1. Make sure effects send and return cables are
good and properly connected.
RUNNING HOT
1. Make sure that the unit has adequate ventilation.
2. Make sure that the impedance selector is set to
the proper impedance.
3. Power tubes may be drawing excessive current
(refer to qualified service personnel).
NOTE: Always set the amplifier to standby when
taking breaks and turn the amplifier off when
not in use. This will extend tube life and improve
long term reliability.
DISTORTION
1. Check the impedance setting.
2. Check the speaker cable for shorts.
3. Check the speaker.
4. Check the signal level at other devices in the
signal path or in the loop.
5. Power tubes may be weak (refer to qualified
service personnel).
BLOWING MAINS FUSE
1. Bad power tube or other internal power supply
component (refer to qualified service personnel).
