TROUBLE SHOOTING:
WARNING: DO NOT REMOVE BOTTOM COVER OR GRILLES...INJURY MAY RESULT. THERE ARE NO USER SERVICEABLE
PARTS INSIDE. REFER ALL SERVICING TO QUALIFIED TECHNICIAN.
NO POWER:
Check the external fuse first. If this fuse is not blown, check the internal circuit board fuse and replace it if
necessary. Remember, always replace fuses with the same type and rating.
NO SOUND:
USE CAUTION when trouble shooting in this situation as the host amplifier may not have a proper load on it.
Turn the amps volume down to a minimum output level so as not to damage the tubes or output transformer while you are looking for
the problem.
Make sure that the footswitch and speaker cables are not reversed and that the speaker connector device is plugged in properly to the
receptacle located at the bottom of the shaft.
KNOCKING:
Knocking is usually caused by one of the bearings being loose on the shaft. There are two 3/32 allen set screws
in the collar of each bearing which must be fastened tightly to the shaft. A small amount of loc-tite is recommended to keep them in
place. These set screws can be accessed more easily by loosening the internal speaker cab on the shaft and sliding it away from
either bearing.
Knocking can also be caused by the internal speaker cab already being loose on the shaft. There are two aluminum blocks inside the
cab and each block has a 10/32 allen head set screw which must be fastened tightly to the shaft. A small amount of loc-tite is
recommended on these screws as well.
