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
