Thank you for the advice. I have booked it in for repair.

PS. There is also a mains fuse that protects the amplifier circuits alone, motors will still run if this fuse has blown. This is FS2 in the schematic, and is the middle one of the three fuses on the power supply circuit board. In my experience, this rarely
blows unless there is a fault in the amplifier, but worth checking.

I don't have 330 schematic in my collection, but I don't believe that there is a speaker fuse. I've had a look at the electrically similar 820 schematic (main difference is no horn speaker every thing goes through a full range 12" speaker in the bottom of
the cabinet). One fault I seem to recall occurring quite frequently in similar Leslie amps is no +28.5 volt supply to the driver stages of the power amp. Often caused by an open circuit R3, 8 ohm 10 watt, resistor on the power supply chassis.
I've found a schematic at . Please remember that there is mains voltage in the power supply, take care if you attempt diagnosis your self. If you don't have the necessary skill and experience, don't even try.

Hello,
I have a Leslie 330 and all of a sudden I'm am not getting any sound. Motors and everything working normally just no sound output. Is there an output fuse??
If any one has any suggestions?please let me know.
Thank you
George
