TROUBLESHOOTING GUIDE
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 selected channel volume
and/or gain controls are turned up.
4. Check to see if the effects loop is engaged
and the level turned down.
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. Look at the front panel preamp tubes to see
if they are lighting up.
WONT SWITCH CHANNELS
1. Make sure footswitch is securely connected.
2. Make sure front panel switch is set to
CLEAN when using footswitch.
BOOST FOOTSWITCH FUNCTION NOT
OPERATING
1. Make sure footswitch is securely connected.
2. Front panel BOOST switch must be ON for
BOOST footswitch to operate.
EFFECTS FOOTSWITCH FUNCTION NOT
OPERATING
1. Make sure footswitch is securely connected.
2. Rear panel BYPASS switch must be in the
OUT position for EFFECTS footswitch to
operate.
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: This amplifier is cathode biased. This
means the power tubes are operating at full
power whether or not you are playing. Because
of this, the amplifier will generate significant
heat when operated for an extended time.
Therefore, 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).
