This page will discuss changing and adding fuses to a Hammond organ.

(Please note that the SuggestedTopics page listed the request as "adding" fuses. While I would assume all Hammonds have fuses already, adding fuses should probably be discussed anyways.)

(Also if anyone knows any model-specific information about fuse types, feel free to add it. I only have experience with one model.)

Changing Fuses

Your fuse types should be listed inside your organ, usually on the power supply chassis. They may be somewhere in the range of 1-3 amps. Make sure you get the exact same type listed - "Slo-blo" or whatever other specifications are listed.

''DO NOT EVER use replacement fuses of a higher amperage. The fuses are there to protect the circuitry from too much current. If your fuses are blowing at their current rating, fix whatever the problem is. Putting in higher-rated fuses will just let more and more current into the organ, and eventually you'll have a nice piece of parlour furniture or maybe a new computer desk for your kids.

Fuses are generally either pigtail fuses or normal fuses. The pigtail ones have a lead on each end and can be soldered onto a terminal strip. Make sure you solder the connection clean. The normal ones have no leads and you need a fuse holder, either in-line (http://www.mcminone.com/product.asp?catalog%5Fname=MCMProducts&product%5Fid=60%2D3735) or pcb/surface-mount (http://www.mcminone.com/product.asp?catalog%5Fname=MCMProducts&product%5Fid=28%2D5782). If you blow fuses a lot, you may want to get a in-line or surface-mount holder to make fuse-changing more convienient.
